Things are quiet at the police station in Ashfordly. Almost too quiet. And it is not going to last. Suddenly two armed men hold up PC Younger and Alf Ventress and lock them up in a cell, while they free a single "guest" without Sergeant Miller noticing anything from behind his desk at the sergeant's office. With PC Walker and PC Bellamy in hot pursuit through Aidensfield they kill a dog and seriously injure a pedestrian. To top it all the police do not even know the identity of the escaped prisoner, who was just detained overnight for being drunk. One more thing bothers Phil Bellamy. He is sure he saw Debbie's late husband Barry in Ashfordly when the pursuit began.
