Step on It! (1922)

Cowpuncher Vic Collins, who is suffering tremendous losses at the hand of cattle rustlers, falls in love with Lorraine Leighton from Kansas City. The rustlers hide their tracks, but Lorraine is suspected of being their leader. Vic, however, will not believe the rumor even though she hits him on the head with a gun butt while he is fighting a rustler. Ultimately, Lorraine discloses that she is trying to capture the gang for sending her brother to jail, and with the help of Lafe Brownell they capture the horse thieves.
