Tell Me Something

The story opens with Detective Jo returning to work after the death of his mother. He is accused of accepting money from a dubious source to pay for his mother’s medical treatment. He denies the charge, but the accusation nonetheless stains his reputation, and the truth of his innocence remains uncertain and unresolved.

Detective Jo is pulled into a brutal case about a serial killer who amputates the limbs and heads of victims, then bits and pieces their bodies together by swapping in new parts for each new murder. The investigation quickly narrows to a beautiful young woman, Shim Eun-ha as Chae Soo-yeon, the daughter of a famous painter. It becomes clear that she knew each of the victims and had dated them in the past, a connection that intensifies Jo’s pursuit as the case deepens. Soo-yeon’s allure and mystery become entwined with Jo’s professional focus, and a tense bond forms as she grows closer to him, blurring the lines between suspect and ally.

Soo-yeon’s past begins to surface as she spends time with Jo. Her only close friend, Yum Jung-ah, who plays Oh Seung-min, is a doctor she has known since high school, and Seung-min reveals troubling personal details: Soo-yeon had attempted suicide several times in the past. This fragility appears to be mirrored in a painting at Soo-yeon’s country retreat, which depicts her as Ophelia drowning—an image that nods to the Pre-Raphaelite painting referenced earlier in the film. With the danger escalating, Soo-yeon moves into Jo’s apartment for safety, heightening the tension and making their closeness feel increasingly dangerous.

Suspicion then shifts toward Soo-yeon’s absent father, revealed as someone who abused her over a long period. The case grows more perilous, and it becomes clear that Jo could become the killer’s next target due to the intensity of his involvement with Soo-yeon. Jo’s colleague, Detective Oh, finds the apartment where the killings have taken place but is murdered in the process. Before dying, he manages to secure a photograph that provides a crucial clue for Jo, turning the investigation in a new direction.

A climactic showdown unfolds, and both Soo-yeon and Jo survive the confrontation. Soo-yeon thanks Jo with a warm farewell before setting off for Paris. Yet the truth comes into sharper relief: Jo realizes that Soo-yeon is, in fact, the killer, having sewn together limbs from each body into one composite. He discovers this gruesome creation suspended in a tall aquarium in her living room and, in a dramatic moment, shatters the glass, ending up wet and backlit in a pose that echoes Ophelia. Soo-yeon’s plane then departs for Paris, and she tells the person beside her that it is her first time in Paris, despite having previously claimed to have studied there. The ambivalence of paradise and danger lingers as the film closes, leaving Jo with the haunting question of who truly controlled the chain of events.
