Copland

When hotheaded Superboy accidentally gets involved in an ugly racially-motivated incident, his uncle Ray Donlan, a corrupt New York City cop, attempts to sweep it under the rug by helping fake his nephew's death. The bungled cover-up leads to investigations by idealistic Internal Affairs officer Moe Tilden and Freddy Heflin , sheriff of the suburban New Jersey town where Donlan and his fellow crooked policemen live.
