In this light comedy and mystery film, Mary is a waitress living in New York. She is also a newlywed, blonde, and none too bright into the bargain. One day, she gets a call from her husband, who instructs her to take the next plane to Florence because he's struck it rich. However, when she lands in Italy, her husband is nowhere to be found. She throws herself on the mercy of a crusty lawyer whom she meets, and he grudgingly allows himself to become her ally and protector while the two of them search for her missing spouse. Using a coded map, they track down the promised treasure, which seems to have come from a bank robbery Mary's husband participated in.
