Maverick - Season 2 - Eps 18: The Rivals
Lydia Linley is a young heiress who yearns for a man like Sydney Carton of A Tale of Two Cities - "a man of warmth, imagination, courage, and a sense of adventure." Jack Vandergelt III (Roger Moore) is in love with Lydia but knows she will have nothing to do with him because he is rich. Vandergelt hires Bret Maverick to switch identities with him in hopes that Lydia will love and accept him for who he is before she realizes he is a Vandergelt. The plan goes smoothly until Jack Vandergelt's father unexpectedly arrives in town.

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.
