While on the run in Utah, smooth cowboy Dan Kehoe (Clark Gable) overhears stories of the notorious McDade brothers.
Three of these career-outlaw brothers were killed on a job two years ago, but one escaped, his identity unknown. The brothers stashed their $50,000 booty on their family ranch, entrusting only their mother (Jo Van Fleet) with details of its whereabouts.
Kehoe leaves immediately to pursue the hidden treasure, ignoring warnings about the feisty mother and her four daughters-in-law still living on the ranch.
The silver-tongued cowboy soon charms both the mother and four gorgeous, man-hungry McDade widows. But which widow’s husband escaped? And do these beautiful women have a motivation of their own?
The battle-axe mother guards her daughter-in-law’s chastity as tightly as the hidden loot, and soon realises that in allowing Kehoe to stay, she has let the fox into the henhouse!
