Jack Lemmon is a happily unmarried man with all the creature comforts one could desire including a wonderful butler who takes care of all his material needs. At a bachelor party for a friend, Lemmon gets drunk and wakes up married to an Italian woman who speaks nearly no English. It totally alters his life. He even changes the cartoon he writes and shifts it from a secret agent to a household comedy. When he begins to have trouble with all of these changes he starts to plot that at least his secret agent cartoon will return to order and plans, in his daily comic strip, killing his wife. When she disappears, the cartoons are used as evidence at his trial.
