The Candidate(2008)

Original title: Kandidaten

Jonas Bechmann, a defense attorney, is a man of the system. Until the day he himself is accused of murder. Taking matters into his own hands, he throws himself into the hunt for a group of blackmailers who threaten to expose him as the killer. But nothing is what it appears to be, and the blackmail links back to his father's death under mysterious circumstances a year and a half earlier.
