Triple Action (1925)

Deputy ranger Dave Mannion is expelled from the force for allowing the notorious Braxton gang to drive diseased cattle past his border patrol. He suspects Eric Prang of being a spy for the gang and sets out to prove it. However, when Dave discovers a herd of the infected cattle, he is shot by Blackie Braxton, who sends the herd and his men to a hacienda run by unsuspecting Don Pío Méndez. Donna, Méndez's daughter, finds the injured Dave and summons his fellow rangers. Prang lures Doris Clayton, Dave's sweetheart, to the hacienda and holds her captive. With the aid of Doris' aviator brother, Dick, Dave parachutes into the hacienda and single-handedly defeats the gang, after which he is reinstated as a ranger.
