Four comedy spy dramas starring Dean Martin as suave American secret agent Matt Helm. In 'The Silencers' (1966) Matt Helm comes out of retirement in order to take on an international agency known as Big O, led by Tung Tze (Victor Buono). When Big O's henchmen attempt to kill Helm, he is saved by another agent known as Tina (Daliah Lavi), and together the pair work together in order to bring down Tze and his evil plot. In 'Murderers' Row' (1966) Helm's nemesis Julian Wall (Karl Malden) has stolen a weapons expert to use his skill for his own nefarious ends. With the help of go-go dancer Suzie (Ann-Margret) Helm does all he can to stop Wall's evil plan. In 'The Ambushers' (1967) Helm aides his colleague Sheila Sommers (Janice Rule) who has had her memory wiped by villain Ortega (Albert Salmi). Meanwhile, Helm must also attempt to retrieve a flying saucer that has been stolen from the American government. Finally, in 'The Wrecking Crew' (1968) a train hijacking in Denmark results in Helm being sent to Europe to attempt to retrieve the stolen gold. However, he has his work cut out for him as Count Massimo Contini (Nigel Green) is linked to the robbery and his fellow agent Freya Carlson (Sharon Tate) struggles to come to grips with the nature of her role.
