The Maverick boys - Bret, Bart, Beau and Brent - are a clan of well-dressed dandies, gamblers who'd much rather make their money playing cards than messing up their fine clothing with actual work.

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.
