Headshot (2012)

Synopsis: A darkly turbulent crime noir from Thai new wave director Pen-ek Ratanaruang, Headshot is an existential thriller, ripe with shadowy paranoia that will turn your world upside-down, literally. This disorienting game of cat and mouse is played out in present-day Thailand, where corruption runs rampant and the good die young. When Tul, a straight-laced cop, is blackmailed by a powerful politician he soon becomes disillusioned by the state of human nature and, in his vengeful condition, is recruited to become a hitman for an iconoclastic group aimed at eliminating those who are above the law. But when a devastating blow turns Tul's vision upside-down, he finds himself engulfed by doubt, unaware of whether the condition is medical or a result of karmic retribution.     Source: Official Site
