A dangerous escaped prisoner is supposed to visit his girlfriend in Sun Hill, and a massive obbo is in place to catch him when he turns up. A bored relief waits in the canteen with P.T.17, and P.C. Ramsey suggests a little game of cards to pass the time. Sgt. Peters and D.C. Carver wait in a van, and while Peters is answering a ""call of nature"", Carver nicks a boy for damaging cars. D.C. Dashwood and W.P.C. Ackland wait in a dance school, where they each take a turn in partnering a dance student. The jealous husband of Dashwood's dance partner storms in and attacks them, taking Mike's gun, which fortunately is unloaded. Ch. Insp. Conway nearly blows the obbo when his impatience causes him to break radio silence, despite D.S. Roach's warnings, but his radio call is just the diversion Dashwood needs to overpower his assailant.
