The episode documents PC Jim Carver's first day at Sun Hill Police Station, during which he is partnered with experienced WPC June Ackland. It isn't specified how long Ackland has been at Sun Hill but, even at that point, it appears to have been substantial, because she is highly respected. The day is an eventful one: the pair's first assignment together leads them to discovering the decomposing body of a woman in her bath. Later, whilst on patrol, Jim encounters a rude youngster (Gary Hailes) and, influenced by comments made by older officers at the station, decides to clip him round the ear. That action results in Carver receiving a reprimand from Sergeant Wilding. However, the boy's father approves of his son's treatment, so no further action is taken. June Ackland and Dave Litten have been in an on-again off-again relationship and, whenever they cross paths, both tend to go silent, making other members of their relief uncomfortable.
