Episodes summary
Episode 1: The Shadow of the Past
The first episode of The Frog, a Korean drama, has an eerie vibe right from the start and it is established by the mysterious portrayal of a vinyl record going around on a turntable, which is in turn followed by violent hints, such as a drowning, a dead person being buried, and silence of screams. In the depths of the woods, Jeon Yeong-ha resides in loneliness on his far-off holiday home, having isolated himself from the world following the death of his wife. He passes the days in relative obscurity while only his faithful companion Yeong-chae pops in to interrupt his stillness to assist Mr. Yeong-ha with errands and business.
On a muddy wooded road, Yeong-ha finds a stalled automobile one day. The mom, Yoo Seong-ah, and her little son, Si-hyeon, appear to be lost within. Yeong-ha tells them that the road ahead leads nowhere and assists them in freeing their car. Soon after, Seong-ah rents a cottage of Yeong-ha’s. She is very polite but her quiet and mysterious character disturbs him. He brings her to the basement for his collection which is not a common practice for him, when she shows interest in his vinyl recordings after spotting his turntable. In a delicate way uniting the two periods, she picks a Bobby Bland record that had the same song as the opening of the show.
The narrative opens in 2001 where Gu Sang-joon and his spouse, Seo Eun-gyeong, are operating a quaint little motel named Lake View Motel. Then one night, Eun-gyeong’s world is turned upside down when we see her panicking and on the phone with the police. Her voice is hoarse and trembling with horror and evokes a sense that something ungodly is taking place in the dark. The officers arrive at a gruesome crime scene: in a room, a motel guest – later identified as serial killer Ji Hyang-cheol – has brutally murdered victims, leaving blood and body parts everywhere. When Sang-jun walks through the police line to witness the massacre firsthand, he is shocked and devastated. His shaking hands and cheeks convey the trauma that will be left behind by that incident. Although this plot seems unrelated to Yeong-ha’s, visual similarities such as the record player, the lake, and the rain imply a secret connection between the past and present.
In the current timeframe, as Seong-ah and Si-hyeon get settled in the cabin, a strong downpour strikes. Yeong-ha’s daughter Ui-seon calls him and asks for permission to bring a male visitor. Even if reluctantly, he agrees. As thunder rumbles outside and the spooky mood intensifies, Seong-ah listens to a Bobby Bland record. Not long after, Yeong-ha sees her again — walking alone on the same desolate road with the same sense of timelessness. When he returns to the cabin, he discovers an envelope that he did not notice before containing $1,000 in cash and still playing on the turntable (though he still did not know this) a record. But after stopping the turntable, he sees blood unexpectedly on his fingers — blurred by his memory of blood on the record cover which he can’t erase. A freezing epiphany takes hold, and when Yeong-ha stares at the blood on the vinyl, in that very moment he knows that something has gone wrong. The episode concludes ultimately asking if the quiet present of Yeong-ha is somehow associated with the violent past that occurred within the motel and what it binds ultimately with a bloody record and a mysterious woman.
Episode 2: Cleaning Away the Truth
The next episode of The Frog opens with the scene of a rain storm in the woods. Yoo Seong-ah makes dinner for her son Si-hyeon. She is working to be calm while in the back of her mind, she has a fearfully unsettled presence just under the surface. The young child Si-hyeon asks, “When will dad come home?” curious in innocence. Seong-ah’s response suggests that feeling like dad is not coming home is not completely normal. This ominous vibe continues into the evening when Si-hyeon plays outside with his toy dog. The atmosphere turns darker when the children are playing outside, and the camera focuses on Seong-ah, who has both blood on her hands and in her hair, and the record begins to play again. The scene transitions to Seong-ah walking outside and into the rain with a blank stare, which was unreadable. The scene and her look leave the audience in total confusion and the protagonists, we are uncertain whether Seong-ah is the victim or perpetrator of the horrific act we just witnessed.
After meeting Seong-ah, Jeon Yeong-ha begins to feel more nervous and suspicious. He nearly runs over Captain Yoon Bo-min, a recently transferred police officer, while driving down the wooded road. Yeong-ha swiftly dismisses her offer of a tissue when she spots blood on his hand, claiming it’s nothing serious. The short yet tight exchange implies that both characters are concealing something. Yeong-ha, unable to get rid of his uneasiness, watches footage from the dashboard camera of Yeong-chae’s automobile, which was parked outside earlier. Although what he sees is not immediately shown in the episode, his reaction – frozen, pale and shaken – tells us that it is something terrible. He decided to hide it instead of informing the police.
After reassuring himself that there is nothing dangerous happening, he shits the door to the basement, cleans the record player, wipes the blood off the vinyl record and burns towels. This scene demonstrates Yeong-ha’s developing moral conflict; he is both afraid and oddly protective of whatever sinister secret is being revealed in his house.
In order to tie the past and present together, the episode also carries on with the flashbacks to the Lake View Motel killings in 2001. After the brutal disclosure of the killings in Episode 1, Gu Sang-jun and his wife, Seo Eun-gyeong, are shown weeping. With the media and police at the motel, Eun-gyeong is upset and distraught outside with police cars and lights flashing, as Sang-jun is left with the guilt of renting the room to Ji Hyang-cheol, the murderer. In the months that follow, their marriage continues to decline; Eun-gyeong moves away from the motel and feels happy in another town, and Sang-jun continues obsessively cleaning the motel in his effort to erase the memory and evidence of the night. Both of these trajectories describe how guilt and anxiety can be felt through time as if Yeong-ha’s actions were remembered back-in-the-day and in the present tense.
Captain Bo-min’s personal connection to the prior case is exposed in the present. She seemed to be still troubled by what transpired at the Lake View Motel years ago, as seen by her perusing newspaper clippings and old photographs of the crime site. She is bound to the same tragic web that seems to circumscribe Yeong-ha’s cabin by this element.
Headlights blare in the dark as rain strikes the cabin, and suddenly, Seong-ah appears from a scarlet car moving forward, unsettlingly and quietly calm. With his heart thumping and thoughts racing, Yeong-ha freezes. Where is Si-hyeon and what is she planning? It is clear from the eerie hum of the record that the past is far from over.
Episode 3 :Yeong-ha Discovers the Hidden Bloodstains
The third episode of The Frog grows more sinister as Jeon Yeong-ha fully embraces and accepts the realities of the nightmare he is experiencing in his tranquil cabin. Following the disturbing dash cam footage he witnessed the night before, there is no way for him to soothe his spirit. The sound of rain, the spinning vinyl record, and dripping blood continually replay in his head. He refuses to call the police despite his growing fear.
The next day, Yeong-ha goes to the cabin rented by Yoo Seong-ah to try to convince himself nothing truly horrible has taken place. However, it seems odd to be silence inside. Seong-ah seemed to be hiding something behind her expressionless face, since she is completely calm and polite. Yeong-ha is freaking out because he has no clue where Si-hyeon is. For this reason, Seong-ah doesn’t disclose what she knows about Si-hyeon to Yeong-ha.
Meanwhile, Captain Yoon Bo-min continues to investigate the 2001 Lake View Motel murders – tempers are flaring. Flashbacks show how Gu Sang-jun’s life was damaged by the ruthless murders, which also gradually destroyed the motel. As Bo-min looks through old documents and pictures, he notices an odd link between the disturbing activities taking place near Yeong-ha’s cabin and the previous murder case.
Yeong-ha sneaks into Seong-ah’s cabin when she is away because he can no longer deny his suspicions. He looks through the rooms nervously and sees evidence that the apartment was cleaned quickly. When he notices traces of blood concealed in the bathroom, his terror transforms into reality. It turns out that a horrific thing took place there, and he’s terrified and petrified.
But Yeong-ha chooses to silence instead of revealing the truth. Unwittingly, he leads himself further into the mystery by cleaning up the evidence. The weird Bobby Bland record plays again as Seong-ah watches him in silence from outside in the rain at the end of the episode.
Episode 4 – Fear Grows Inside the Rainy Woods
Episode 4 begins with Yoo Seong-ah spying on Jeon Yeong-ha from afar under the rain after learning that he had cleaned the blood from her cabin. This is exactly where last week’s episode ended. Yeong-ha realized that was the limit he had crossed now. He is terrified and riddled with guilt, but he is trapped, because to expose Seong-ah would also be to expose himself.
The next day, the cabin is becoming more and more claustrophobic. Yeong-ha is still haunted by Si-hyeon’s disappearance and the blood he encountered in the bathroom. He starts to turn away from Seong-ah, but her composed demeanor just serves to heighten her fear. Cooking, being courteous, and listening to the same creepy Bobby Bland music that now seems to be associated with death itself, she still acts as though she were a frequent visitor.
As everything is going on, Captain Yoon Bo-min becomes increasingly suspicious of the odd activities taking place close to Yeong-ha’s land. Based on her intuition, she believes that the current occurrences are quite similar to the horrific atrocities that occurred at the Lake View Motel in 2001. Through flashbacks, we have witnessed Gu Sang-jun’s demise after the Lake View killings changed his life. As customers stopped coming to Lake View, Gu Sang-jun became lost trying to forget the past with all the rumours going around the community about the Lake View murders.
Fearing that he might find something terrible related to Si-hyeon, Yeong-ha surreptitiously examines the woods around the cabin in the current timeframe. Every sound in a bush makes him more suspicious. An ominous presence is haunting us due to the ever-present quietness of the woods, the darkness inside the woods, and the incredibly violent rain.
Emotional intensity reaches its pinnacle when Seong-ah suddenly appears next to Yeong-ha, still and silently standing still amongst all of the ominous presences found in these woods. Asking Yeong-ha irrelevant types of questions, which could be interpreted as ominous warnings, Seong-ah gives no visible display of emotion. Yeong-ha realizes that although he is terrified by Seong-ah, he finds her to be somewhat appealing.
One of the most ominous things that happen near the end of the show may hold the most frightening revelation concerning Si-hyeon’s character than Yeong-ha ever expected.
Episode 5– The Woods Reveal Si-hyeon’s Fate
The darkness surrounding Yeong-ha’s cabin no longer feels like ordinary silence — it now feels alive. Since he found the blood in Seong-ah’s cabin, Yeong-ha has been unable to think straight. With no sleep at night, it’s constantly raining outside, and he can hear the old vinyl record’s sound playing over and over again, two things are starting to erode his mental state as well as his ability to feel safe, even at home, because from his perspective, someone is always watching him from somewhere inside or outside of his house.
Yoo Seong-ah acts oddly composed after their unsettling encounter, carrying on with her daily activities as if nothing had happened. Yeong-ha is more uneasy by her stillness than by her rage. While Captain Bo-min links the mysteries of the cabin to the horrible deaths at the Lake View Motel, Yeong-ha, overcome with suspicion and horror, pursues Seong-ah into the dark, wet woods.
The terrifying moment that he was never ready for then arrives. Yeong-ha finds proof that Si-hyeon suffered a horrible fate deep beneath the jungle. For Yeong-ha, the shock and panic take over his body. He can’t process what he’s just seen when Seong-ah appears behind him in a low voice. She stares at him without raising her voice or displaying any emotions. At that horrifying moment, he realizes Seong-ah has always been the real menace, not the secret.
Episode 6– Yeong-ha Falls Deeper Into Seong-ah’s Darkness
In the aftermath of Yeong-ha’s horrific discovery, a peculiar atmosphere lays over the trees. The rain continues to pour, the density of the air remains increased further, and the once serene cabin now feels menacing and filled with concealed objects. After discovering Si-hyeon’s connection, Yeong-ha’s mental state has been deteriorating. It’s as if his brain is overheating. He can’t sleep. He’s started contemplating every instance where he’s encountered Yoo Seong-ah, and is trying to process how someone could keep such a disturbing secret while maintaining a front of such perfect composure.
As Seong-Ah goes through her everyday routine in the cabin, cooking, playing her old records, or simply expressing her calmness and patience, Yeong-Ha finds it appalling that from his perspective, everything appears to remain how it should. The calm and quiet only worsen as time passes. The longer he looks at her, the more he sees that her silence hides something other than anger: darkest of all secrets. Each time their eyes meet, he feels that she knows all of his thoughts of fear.
Meanwhile, while all of this is happening, Capt. Yoon Bo-Min continues to investigate the strange relationship between the multiple murders committed at the Lake View Motel both years ago and in the present. Flashbacks to Gu Sang-Jun’s horrible murder tell of his total life being destroyed due to the serial killer and the fear/shame he experienced after it happens, just as Yeong-Ha is currently feeling.
Yeong-ha gets stuck in Seong-ah’s horrific world while he looks around the cabin for solutions. A heated discussion over Si-hyeon soon gets out of hand, exposing Seong-ah’s deadly side. In the meantime, Captain Bo-min unintentionally enters the same darkness engulfing Yeong-ha as he makes his way through the stormy woods toward the cabin.
