Renegades of the Rio Grande (1945)

Texas rancher Buck Emerson (Rod Cameron) poses as a bank robber in order to bring to justice the outlaw gang that killed his Texas Ranger brother Johnny Emerson (John James.) The trail takes him across the Rio Grande River into Mexico to the Salezar ranch where, unknown to the pretty owner, Dolores Saleza (Jennifer Holt), the gang is using as their base into robberies in Texas. Complications arise when Texas Rangers Cal Benedict (Eddie Dew) and Trigger Bidwell (Fuzzy Knight) think he is one of the gang members.
