The Big Heat

A police officer seems to have committed suicide, but Detective Dave Bannion thinks there's more to the story. After talking to the man's mob-connected mistress, Bannion discovers far-reaching corruption that leads all the way from the police station to kingpin Mike Lagana. But when the policeman's lover is killed, it becomes clear that crossing Lagana is a dangerous thing to do. Soon Bannion finds himself marked for death and his family in mortal danger.
