Blankman

Darryl Walker (Damon Wayans) is a clumsy nerdy repairman, who is a genius and Batman (TV series) fan. Darryl has a pure heart and an optimistic Pollyanna personality. He is childishly naive to the realities of living in an inner city neighborhood. The area suffers from political corruption and the police are on strike. It takes the murder of his grandmother, an avid supporter of Alderman Marvin Harris' anti-corruption campaign for Mayor, by members of mobster Michael Minelli's gang, to awaken him to the realities of his city's urban decay.
