James Garner and Debbie Reynolds star as hapless American parents adrift on the French Riviera at the height of the 1960s who discover life, love and How Sweet it Is. When Grif and Jenny Henderson's (Garner and Reynolds) 20-year-old son follows his girlfriend to Europe, the parents follow the boy to keep him out of trouble. But when Jenny Henderson gets conned by Mr. Tilly (Terry-Thomas) into renting a villa that isn't vacant, the Henderson's depend on the hospitality of the villa's amorous owner. Now lust, jealousy and the counterculture collide in this hilarious comedy of errors.
