Lucas McCain and his son Mark become step-parents of a sort when they try to help out a local girl, Leona Pickford Bartell, a singer at the saloon. Her bible-spouting violent husband Wood Bartell has been hunting her down intent on getting their baby girl away from her. Lucas offers to take care of the baby at his ranch until Wood hopefully leaves town. He has no intention of doing that and along with his bull whip, is intent on getting what he rightfully believes is his. It's left to Lucas to sort it out.
