From Oscar-winning writer and director Martin McDonagh comes a star-studded, blood-drenched, black comedy. Marty (Colin Farrell) is a struggling writer who dreams of finishing his screenplay Seven Psychopaths. All he needs is a little focus and inspiration.

Billy (Sam Rockwell) is Marty's best friend, an unemployed actor and part time dog thief, who wants to help Marty by any means necessary.

Hans (Christopher Walken) is Billy's partner in crime. A religious man with a violent past. Charlie is the psychopathetic gangster whose beloved dog, Billy and Hans have just stolen. Charlie's unpredictable, extremely violent and wouldn't think twice about killing anyone or anything associated with the theft. Marty is going to get all the focus and inspiration he needs, just as long as he lives to tell the tale.
