Brad Canfield (Tim Holt) plans revenge when the Tonto Rim band swoops down on one of his coaches, murders the driver and kidnaps a passenger, Lucy Dennison (Nan Leslie.) Brad and his Irish-American partner Chito Rafferty (Richard Martin) learn that the Arizona Rangers have never found the gang's hiding place. Gang member Tony Patton (Tony Barrett) is in the Tonto jail and, posing as an outlaw with Chito as a Ranger, Brad gets himself locked up and then stages a jailbreak, taking Patton with him. Patton leads Brad to the ranch of John Dennison (Tom Keene as Richard Powers), the gang leader, whose sister Lucy is being held prisoner. Patton introduces Brad as a new outlaw recruit. Brad tips Sheriff Curtis (Harry Harvey) the location of the hideout, but the suspicious Juanita (Carol Forman), who has been guarding Lucy, trails him and warns Dennison. Brad returns to the ranch and is taken prisoner, but he gets free, kills the guard and holds the gang trapped until the posse arrives.
