DI Deakin leads CID and Uniform on a series of disasterous raids to catch alleged DSS fraudsters, while PC Polly Page is given the boring task of serving a court order. As she does so, she hears scratching at the wall from the house next door, which they believe is a trapped dog. With the help of the RSPCA, they force entry and discover a young Spanish woman named Lola imprisoned in a hidden cellar. The owner of the house, Ricky Lee, insists that Lola is a fugitive from a Dutch prison who stowed away in his van and took refuge in his house. When Lola disappears from the hospital, Page and DC Kerry Holmes pay Ricky Lee another visit. Page is suspicious and asks to see the cellar again, but Lee attacks them. Once subdued, they find Lola in the cellar once again, and it looks as if Lee was planning to kill her.
