The Big Heat (1953) Glenn Ford, Gloria Grahame, Jocelyn Brando

Dave Bannion is an upright cop on the trail of a vicious gang he suspects holds power over the police force. Bannion is tipped off after a colleague s suicide and his fellow officers suspicious silence lead him to believe that they are on the gangsters payroll. When a bomb meant for him kills his wife instead, Bannion becomes a furious force of vengeance and justice, aided along the way by the gangster s spurned girlfriend Debby. As Bannion and Debby fall further and further into the Gangland s insidious and brutal trap, they must use any means necessary (including murder) to get to the truth.
