Double Cross

In this action film, an officer is thrown off the force by his father the chief of police. The bitter ex-cop then joins a racketeering operation. The ring leader assigns him to drive a truck-load of armed hoods to ambush his father. Unbeknownst to the crooks, the ex-cop is still active on the force. The whole affair was a ruse to capture them. The brave cop succeeds in warning his peers of the ambush and the bad-guys die in a hail of bullets.
