Shackley was an upright police officer, but he was never appreciated by his superiors. it was not until he was nearing retirement that he took over a major case from the new director and asked him to go to another city to bring Molly, an important witness in a drug case, to Phoenix to testify in court. When he was about to return to Phoenix, he was chased by the police and gangsters one after another, and all the signs made them understand that it was the police in Phoenix who colluded with the crime gang. To kill them, the upright police officer was enraged and went back to Phoenix for revenge with Molly. They deliberately informed the enemy of the route. Molly and Molly drove into Phoenix all the way in a big bus full of tin. Hundreds of police officers were ordered to stop the car, and the car was devastated. In the desperate situation, the two men hugged each other out of the car door, and the vicious police chief ordered the police to shoot them. Frightened by the righteousness of Shackley and Molly, there was no one to listen to, and in the end, justice prevailed over evil. The evil police chief died under Molly's gun, and the two hugged each other into the distance.
