Michael Neumann Klaus Lowitsch gives a riveting performance in the title role of this intense German drama, portraying a ruthless veteran cop who enacts a contest of wills with his rookie partner in a seedy police outpost on the edge of an abandoned precinct. The arrival of a runaway teenage prostitute sparks the already volatile mood between the two men, until the bitter, alienated Kaminsky finally unleashes his pent-up rage and frustration in a horrifying act of brutality. The first feature by writer director Michael Lähn is a chilling, claustrophobic one-set psychodrama benefiting from a mood of almost histrionic moral decay, but let down by an unfortunate (and unbelievable) resolution in which everybody kills everybody else. Approach with caution.
