D.S. Roach spots a drug deal taking place on the Rochester Estate, but he, Carver and Dashwood fail to catch the dealers. P.C. Haynes and P.C. Ramsey spot the escaping car in their panda and give chase, but the dealers' car hits a little girl before crashing into a skip. Haynes loses one of the suspects when obstructed by some punks, but the driver of the car, Mickey Squire, is arrested. With Burnside on leave, Ch. Insp. Conway allows Ramsey and Haynes to continue with the case. Ramsey is pleased as he thinks it may get him back into C.I.D. He and Haynes play good-cop/bad-cop to get a confession, and Haynes goes undercover at a party to find the escaped passenger and the main drug supplier. C.I.D. raid the supplier's luxurious apartment and discover a huge amount of drugs and stolen goods in his garage. P.C. Melvin and W.P.C. Brind attend a fracas at a laundrette. Melvin slips on some soap, leaving Brind to take charge.
