A 'Down on their luck' aunt (Eileen Heckart) and niece (Katharine Ross) are on their way to San Francisco. When Aunt Hattie and her niece, Liz stop in Dodge City, Hattie is forced to support Liz's dreams of a wealthy lifestyle by taking a job at the Longbranch Saloon. There, she meets a farmer, who soon falls in love with her and asks her to marry him and stay in Dodge. He also says Liz can live with them. However, when Liz finds out that Hattie plans to forgo the wealthy San Francisco lifestyle she envisioned for the hard life as a farmer's wife, and has no money to support herself without Hattie's help, she takes matters into her own hands in a most deadly plan.
