Charles Bronson portrays Nick Colton, a tough bush pilot who is hired to spring innocent man Jay Wagner (Robert Duvall) from a Mexican jail. Unfortunately for the both of them, Wagner was framed for murder by wealthy Harris Wagner (John Huston), who has the financial resources to make the escape very difficult for the both of them. Riding high on the success of the previous year's DEATH WISH, Bronson picked this as his follow-up. Director Tom Gries also directed Bronson the same year in BREAKHEART PASS.
