The Dead King (2015)

Chasing down wretched souls who leave no trace is the curse of Detective Bosworth. He really just wanted to call it a night, but a dubious phone call just before midnight lures him back into the game. Cornered by his nemesis, Bosworth finds himself the target of a bizarre power play.
A black-humored parable of human hubris. A precisely timed finale in which the opponent's vanity becomes the most unpredictable downfall.
