Nearing the completion of his sentence in Sing Sing prison, Paul Vitti's life is threatened by assassins and corrupt guards while incarcerated. He fakes insanity and starts singing showtunes from West Side Story to get the attention of Ben Sobel, who previously hung up on him while attending his father's funeral. The FBI calls in Ben to see if Paul is really insane. It turns out Vitti is faking it, but Ben doesn't find this out until after he's left Sing Sing. Needing some therapy himself after his father's death, a grieving Sobel talks Vitti into finding a regular job (per FBI request). Vitti attempts to find a legitimate job (he tries his hand at a car dealership, a jewelry store and a restaurant), but his rude manners and paranoia mess things up.
