Darryl Walker (Damon Wayans) is a clumsy, nerdy repairman, and a longtime fan of Batman. Darryl has an overly optimistic, almost Pollyannish personality, and is childishly naive to the harsh realities of living in the inner-city: the city's leadership is corrupt and the police are on strike after going without pay. It takes the murder of his Grandma Walker – an avid supporter of Alderman Marvin Harris' anti-corruption mayoral campaign – by mobster Michael "The Suit" Minelli's henchmen to open his eyes to the urban decay all around him.
