PC Polly Page returns to duty at Sun Hill following her breakdown. She is assigned to the CSU, and paired with PC Cathy Bradford. Page and Bradford investigate a stalking case which becomes far less straightforward when both parties accuse the other of harrasment. PC Gary Best goes undercover as a schoolboy to investigate drug dealers targetting the school, but when his information leads to a raid, Abigail Nixon blows his cover. Arrested for assault by PC Luke Ashton, Acting DI Nixon and Sgt. Murphy witness Abi putting the moves on a befuddled Ashton, making Sgt. Matt Boyden's denials slightly more believable. PC Jim Carver spends the day with the mother of murdered teacher Sonia Graham, but his professional role as Family Liaison Officer is comprimised when they end up in bed together.
