Deadly Companions is a 1961 American Western directed by Sam Peckinpah. The film opens in Gila City, Arizona with a bank heist being carried out by Yellowleg (Brian Keith), Turk (Chill Wills), and Billy Keplinger (Steve Cochran). Yellowleg earned his nickname from the time he served in the Union Army during the Civil War. He met Billy and Turk when he saved their lives in a dispute over a card game. During the heist, Yellowleg accidentally shoots and kills the son of a cabaret dancer named Kit Tildon (Maureen O'Hara). Yellowleg is remorseful and when he discovers that Tildon plans to bury her son in Apache Territory, he decides to accompany her. Tildon reveals that she plans to bury her son in the same area as where his father was buried. Yellowleg asks Sam and Billy to accompany him and after they agree, the troupe sets out for the dangerous land inhabited by the Apache Tribes.
