A two-bit criminal takes on the Mafia to avenge his brother's death in this drama based on a novel by Donald E. Westlake. Earl Macklin (Robert Duvall) is a small time criminal who is released from prison after an unsuccessful bank robbery only to discover that a pair of gunmen killed his brother.
As it turns out, the bank that Earl and his brother hit was controlled by gangster Mailer (Robert Ryan). Macklin learns that he's on the mob's hit list as well, so he teams up with his old partner Cody (Joe Don Baker) to take on Mailer and his second in command, Jake Menner (Timothy Carey).
The Outfit also features a top-notch supporting cast, including Karen Black, Sheree North, Joanna Cassidy, Richard Jaeckel, and Anita O'Day; Marie Windsor and Elisha Cook, Jr. also appear, 18 years after their memorable turn together in The Killing.
