Jenny Henderson discovers that Davey, her son, has arranged to accompany Bootsie, his girl friend, on a European tour, and arranges to have Grif, her photographer husband, assigned to cover the tour for a magazine. Deciding that she too wants to spend the summer in Europe, Jenny makes a down payment on a Riviera villa being rented by real estate man Gilbert Tilly. Once in Europe, Grif and David set off on the photography assignment while Jenny proceeds to her villa. Upon arrival, she learns that she has been swindled: the villa's owner, wealthy playboy Philippe Maspere, is in residence. Delighted with his unexpected guest, Philippe persuades Jenny to stay on and presents her with a turquoise bikini. When Jenny visits Grif in San Remo, she is disturbed by his attentiveness to an attractive guide, Nancy Leigh, and is further irritated by his indifference toward her sharing the villa with a man. Feeling unloved and middle-aged, Jenny returns to Philippe, but any possible romance is curtailed when Grif arrives in the tour bus, catches sight of Jenny cavorting in her bikini, and belts Philippe. Later, while driving back to San Remo, Jenny and Grif are arrested for stealing the bus and are thrown into jail. Miss Leigh quickly bails out Grif, but Jenny is left in a cell with some prostitutes. When the bordello owner, Mr. Agatzi, comes to retrieve his girls, Jenny is included in the lot and taken to his brothel. Eventually, Grif and David arrive, and a fight ensues; but Jennie and Grif are reconciled.
