Holly Houston rides into town with three small children and a plan to find herself a husband, so the judge won't take the kids from her. Her target? Jason Bolt.
She manages to convince most of the town that Jason IS the father of the three children and that he'd promised to marry her. She then leaves the children with the brides and disappears from town.
With the town mostly taking Holly's side, Jason tracks her down and tells her that he will teach her how to be a lady so that the judge will not take the children from her. She accepts his offer, hoping that he will marry her once she's more ladylike.
At the custody hearing, everyone finds out that Jason is not the father and that Holly is not the mother. (She's the aunt.) The children will be sent to Ohio to live with their grandparents and Holly decides to accompany them there.
In the final scene, Jason receives a note from Holly telling him how things went and asking him to introduce her to the eligible Mr. Aaron Stempel when she returns.
