When an unremarkable comedian somehow finds himself on the wrong side of the mafia he flees Detroit for Chicago and takes on the new name 'Mickey One' (Beatty), a name picked up from a stolen social security card. In Chicago Mickey lies low, living a rough life in a rough part of the city in an attempt to avoid being hunted down by the mafia. Despite these fears, Mickey eventually finds himself drawn to the stage once again. Knowing any level of publicity will likely lead the mafia straight to him, he tries to determine what exactly he has done to bring the mob's wrath down upon himself.
