CHASER, THE (2008)

A former cop turned desperate pimp, Joong-ho (Kim Yoon-seok) is frustrated that his girls are running out on him. When his last call girl, Mi-Jin (Seo Young-hee) disappears, Joong-ho makes a harrowing revelation - there's a sadistic serial killer at play. Traversing the shadowed streets of Seoul, an intense cat-and-mouse pursuit ensues as Joong-ho must track down the killer in a desperate race against the clock. Equal parts disturbing and tense, acclaimed director Na Hong-jin's debut feature is a masterpiece thriller that delivers unexpected twists in the face of visceral horror.
