Fleeing a band of angry Native Americans, Bret takes shelter in a way station where a family of nasty outlaws are planning their bloodiest deal.

Beau Maverick (played by James Garner), father of Bret and Bart announces that he is getting married. The Maverick boys discover that the marriage is a business arrangement, not a love commitment. The young girl, Josephine St. Cloud is being forced by her father to marry the older Beau Maverick. The brothers set out to sabotage the wedding plans, not knowing that Beau Maverick already had a plan.

Bret is fighting a murder charge. But when he meets his lawyer — a numerologist, astrologer and bungler — he knows his number is up.

Inheriting a stagecoach line from Uncle Micah is only the beginning of financial problems for the Maverick brothers.

Bart substitutes a rock-filled suitcase for a fortune in gold to foil hijacking plans of phony sheriff Dan Trevor (Peter Breck).

Thinking all's well with the world after he cleans up in a card game, Bart offers to help a troubled young woman.
