Based on the novel by legendary pulp writer Jim Thompson (The Grifters), The Killer Inside Me tells the story of a handsome, charming, unassuming small town sheriff’s deputy named Lou Ford (Casey Affleck). Lou has a bunch of problems. Woman problems. Law enforcement problems. An ever-growing pile of murder victims in his West Texas jurisdiction. And the fact that he’s a sadist, a psychopath and a killer. When suspicion begins to fall on Lou, it’s only a matter of time before he runs out of alibis. But in Thompson’s savage, bleak, blacker-than-noir universe, nothing is ever what it seems, and it turns out that the investigators pursuing him might have a secret of their own.
