However, the bounty hunters are being picked off, ""Ten Little Indians"" style, one by one. The pair must figure out who is responsible, and how to stop them.

Brisco and Bowler arrive in Hard Rock, and foil local thug Roy Hondo from breaking up the restaurant run by Bowler's ex-girlfriend Lenore. It turns out Hondo is running a protection racket.
