Henry Dussard (Dean Jones), a young American, inherits a picturesque but badly neglected olive farm in southern France and is determined to make it operational again despite cautionary advice from the local priest (Maurice Chevalier) and a pretty villager (Yvette Mimieux). Desperate for laborers, the inventive Dussard turns to the zaniest crew of olive pickers ever recruited ... four mischievous monkeys! As former members of an Air Force space team, these intelligent chimps quickly pick up on their new responsibilities ... but prove to have a turbulent effect on the local townspeople. Endless hilarity results in this slapstick family comedy!|One critic wrote of the film: "If a chimpanzee is cute, does it not follow that a quartet of them will be four times as cute?"
