Left out of the cast list here is the guest star, Efrem Zimbalist, Jr. Zimbalist plays Dandy Jim Buckley, a fellow gambler who admires Maverick's integrity but doesn't share it.
The two meet up when Bret is robbed and tossed overboard a riverboat headed up the Missouri River to Deadwood. They discover they both have been victimized by Tony Cadiz. They partner up in an elaborate series of schemes that includes digging out of jail, large trees and tame skunks; but they finally wind up in Deadwood to confront Cadiz.
Garner and Zimbalist have an easy chemistry that leaves you wishing for another appearance of Dandy Jim.
