In a rain‑slick city that clings to the river’s edge, a seasoned forensic pathologist is poised to leave the morgue behind and spend precious time with his daughter, who has just returned after years abroad. The quiet anticipation of retirement is shattered when a mutilated body drifts downstream, pulling him back into the relentless precision of his trade one last time. The atmosphere is cold and clinical, yet the lingering hum of the river hints at deeper currents beneath the surface.
Detective Min of the homicide unit arrives with a rookie partner, setting the tone for a partnership that balances meticulous procedure against intuitive urgency. Their investigation quickly locks onto an outspoken environmental activist, Lee, whose radical stance and cryptic confession cast a shadow over the case. The clash of professional worlds—medical exactitude and police instinct—creates a tension that feels both personal and societal, as each character is forced to confront the gray areas of truth and duty.
As the inquiry deepens, a chilling twist surfaces: the pathologist’s own daughter is taken hostage, thrusting him into a stark moral dilemma. With his family’s safety hanging in the balance, he is forced to navigate a cruel psychological battle where every hidden secret could tip the scales toward resolution or ruin. The film pulses with a brooding intensity, letting the audience feel the weight of each choice without revealing the outcomes.
The tone remains stark and unflinching, blending procedural rigor with a haunting psychological thriller vibe. Themes of guilt, loyalty, and the cost of justice linger like the river’s fog, inviting viewers to ponder how far one will go when the lines between victim and perpetrator begin to blur.
