Probationary PCs Ben Hayward and Roz Clarke arrive for their first day at Sun Hill, and are subjected to a series of wind-ups by the relief. Boyden tricks Clarke into thinking that he has hit a pensioner in the surveillance van, while Stamp and Quinnan subject Hayward to the ride of his life in the area car. Hayward manages to stop a curb-crawler who evades capture, but his arrest is thwarted by Hollis. Meanwhile, Hagen and Rickman spin Clarke a story about 'nipper' Cryer, the famous bum-pinching sergeant, and Klein gets Worrell to be pretend to a dead body in order to wind up Hayward. However, the joke backfires when an angry and upset Hayward is punched in the face by Stamp.
