The Outlaw's Daughter.

Led astray by outlaw leader Jess, the "outlaw's daughter" Kate joins Jess' gang and follows in her dad's footsteps. Town marshal Dan tries his best to reform the girl, but this proves difficult inasmuch as Kate holds Dan responsible for her father's death. Only after most of the bad guys have been decimated by Dan does Kate discover the true identity of her dad's murderer. Having fallen in love with Kate, marshal Dan offers to let her escape prosecution, but she's made of sterner stuff than that.
