W.P.C. Ackland and P.C. Stamp arrive at a brothel, where they find Jo Whitney, the daughter of a prominent local councillor, soaked in paraffin and threatening to set herself and the building on fire. Jo is a prostitute and a drug addict - but she hasn't had a fix for three days, and is highly agitated and strung out. Ackland stays with her to try and talk her round, while Stamp calls the fire brigade. There is a struggle to gain control of the lighter, and as a result, the flat catches fire, but Stamp manages to get both women out. Almost immediately after this ordeal, C.A.D. asks June to move on to deal with a burglary (after a cup of tea of course).
