Angelo "Snaps" Provelone (Sylvester Stallone) is a profitable gangster during the Prohibition. He promises his dying father that he'll go straight, and the movie is set on the day he has a meeting with bankers to do just that. However, everything goes wrong--he is woken up by his accountant who tells him he's been stealing from him in order to have enough money to marry his daughter, Lisa (Marissa Tomei). He promises to give it to her in a suitcase full of jewels. She hears of someone's proposal and says she is pregnant so she can get out of the house. However, there is more than one daughter, and several suitcases. Maids, cops, bankers, mobsters, linguists, and ex-lovers run around the house all day and are finally all discovered in the hilarious conclusion.
