After being summoned to Denver by the Sheriff to help catch a bank burglar before he can break into the biggest bank West of the Mississippi, Bret runs into his old friend, Foursquare Farley. Foursquare has the unusual characteristic (for the show) of being a really nice guy whom everyone likes. Of course, things are not what they seem, and Bret's task turns out to be at odds with Foursquare's interests, leading to a complex series of ever-funnier plot twists. Like many Maverick episodes, there are no female characters in Greenbacks, but there are plenty of laughs and clever plot devices. Typical of our anti-hero's self-aware humor is the following exchange:
Bret (fondling money in the vault): Oh, I wish I were the brave type.
Foursquare: You mean the dishonest type, don't you?
Bret: No, the brave type.
Fans will not be disappointed with this excellent episode.
