Isaac Hayes makes his first appearance as ex-convict Gandolph "Gandy" Fitch--and in the bargain, contributes his own character's theme music. Released from San Quentin after 20 years, Gandy hires Jim (James Garner) to prove that he was innocent of the crime for which he was convicted: namely, the murder of his girlfriend Lila. Though he's fairly certain that Gandy was guilty, and despite his resentment over his client's insistance upon calling him "Rockfish", Jim accepts the job...and the process nearly meets his doom at the hands of Lila's vengeful family.
