Another one of the many films Wilder made with Jack Lemmon. Lemmon is a high strung American executive always in a hurry and unable to understand the Italian way of slowing down and enjoying life. He goes to an Italian island to collect his father who died in a car accident. His father died with his secret mistress beside him. The daughter, Juliet Mills, of the woman has come to the island from England to collect her mother too. Lemmon learns of his father having a mistress from her and from the hotel staff. Everyone at the hotel including Clive Revill, (now an Italian) the manager of the hotel, knows that the affair had been going on for a month every summer for ten years! Lemmon struggles with these facts he never knew about his father and deals with many humorous complications in arranging to take his father home to a big media covered funeral while keeping the affair a secret. All the hotel staff think the younger couple look like his father and her mother, so of course a romantic situation develops. Armbruster Jr. (Lemmon) says he's hip enough to realize there's nothing wrong with a one night stand, or even many short affairs, but a long-term affair like his father had, that's cheating on his mother. Hhmmm!? Miss Piggott (Mills) wants to make the point that their long-term affair was based on love, that they could enjoy life and be happy in Italy, and that it was beautiful. She suggests they be buried side by side on this Italian island where they were happier. Miss Piggott eventually helps Armbruster Jr. learn a bit of Italian and enjoy life. When a servant knocks at your door in the hotel to clean your room and asks "permiso," you can answer "avanti," or "come in," "your permitted." It is by this little play on words that Lemmon and Mills realize they are in love. Lemmon's character has a wife at home too, but the film ends with these two new lovers basically promising to meet each summer on this island like their parents did. It was a colorful quirky movie, but when you think about it the message is that infidelity isn't that bad.
