September 15, 1977
After a security guard is murdered during the theft of a valuable emerald collection Barnaby and J.R. are hired to investigate. What they unearth is a madam, her low-life boyfriend, and a call girl carrying out her part in a scheme to rip-off unsuspecting men of their valuables.
Barnaby travels to the small town of Las Mesas looking for a missing woman. He finds her, but he's taken captive along with her and several town residents by a group of men waiting to steal $250,000 from an armored car that is going to come through town. Their only hope to escape lies with J.R.
This episode was likely a "backdoor" pilot for a new series that shelved before production.
