In this light romantic comedy, Tommaso is a charming restaurant owner with a roving eye and a similarly roving hand. He just can't keep away from the ladies, even when he is engaged to a woman he loves very much. When she discovers this, she tries to give him a chance to straighten out, but eventually they call the engagement off.
However, the restaurateur simply cannot abide it when his lady-love begins dating another man. Meanwhile, he has been subjected to the somewhat sinister amorous advances of a friend's younger sister, who poisons him to show her love.
