Maverick - Season 4 - Eps 17: Family Pride
In New Mexico, Beau Maverick is taken for over $4,500 ($4,000 of which belong to his friend Jerry O'Brien) by con artists Warren and Crippen and Warren's granddaughter Rosanne. Beau tries to recover the money and even takes the threesome to court, but they outsmart him every time. Beau is so demoralized by the constant defeats, he believes he has disgraced the Maverick name - until Rosanne tells him that her grandmother was a Maverick.

Synopsis
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. Sly and clever, none of the Mavericks are much for acts of derring do, but they can be courageous when the situation calls for it. Most often, however, they live by their wits and considerable charm.
