McCloud - Season 4 (1973)

Four elderly outlaws hold up McCloud and Broadhurst, who have just robbed a bank during a public demonstration to show the effectiveness of new bank and police procedures. As the robberies continue, and after a sophisticated computer draws the conclusion that the gang's leader is "the son of Butch Cassidy," the NYPD is sent into fits trying to track them down.

McCloud gets himself involved in a series of murders of high-class escorts after a body he discovers in a senator's flat mysteriously disappears.

When McCloud and Clifford wind up together at a police convention in Hawaii, Clifford is framed for murder. With the help of Clifford's ex-fiancee, several of Clifford's cop friends who are also at the convention, and a Honolulu police detective, McCloud must find out who framed him and why.
