Hunter (1977)

James Hunter and Marty Shaw work as undercover counterespionage agents on the international scene. Their leader is General Baker. As members of an elite, five-member unit known; only to their boss, General Baker (Ralph Bellamy), Jim and Marty engage in perilous counter-espionage
and anti-terrorist operations and still have time for a bit of romance. As a cover, Hunter runs a bookstore in Santa Barbara and Marty is a model. Jim has been persuaded to return to government service after quitting the CIA because of disillusionment over some of the operations of the CIA and FBI.
