In JIMMY HOLLYWOOD a young Jimmy Alto (Pesci) moves to Hollywood from New Jersey to try to make it as an actor. With circumstances progressing nowhere, an unemployed Jimmy resorts to stealing from his girlfriend when he needs money. When someone breaks into his car and steals his radio, he and his friend William (Slater) begin staking out the neighborhood in hopes of catching the thief. This new operation gives birth to the S.O.S. (Save Our Streets) organization that ultimately gives Jimmy a sudden taste of fame.
