Gene and Pat rescue a girl who was being chased by three men. She claims to be Tonia Castelar. Once in town, Gene runs into the three outlaws, and starts a fight. When a tax collector hears Gene and Pat are after "El Avengador", he has them guard a stage the next day, but Gene refuses. While Pat stays with Tonia, Gene and the sheriff find a stage attacked, and the tax collector killed. Pat learns that Tonia is the leader of an outlaws, and asks Gene not to arrest her. She lets Gene and Pat go, right when the outlaws, led by Wade Morgan, attack. The sheriff arrives and finds out that Wade is El Avengador, and Tonia is promised a pardon.
