When a man falls to his death in the mountains, detective Hae-joon (Park Hae-il) is put on the case. He questions Seo-rae (Tang Wei), the victim's wife, who seems unmoved by her husband's death - making her the perfect culprit. But the detective is thrown off balance by the budding feelings he is beginning to have for her...

"The closer you look, the harder you fall": the trailer serves up a tantalising taste of a thrilling reunion with Korea's master of suspense. But this time around, Park Chan-wook has us hooked in the subtle exploration of Hae-joon and Seo-rae's mutual fascination. One is a methodical, proud, and ambitious up-and-coming police officer. The other is a woman who is unhappy in love, but honest and brave in the face of suspicions surrounding the part she had to play in the case.

The characters' psychology lies at the heart of the narrative. Without ever realising it, the viewer is slowly immersed in the tale, led deep into a setting where sea and mountain collide. The director is joined by the loyal team that helped catapult him onto the global stage: Chung Seo-kyung for the screenplay, Kim Ji-yong on photography, and the talented Cho Young-Wuk for the score.
