Les Mitcham and Phil Andrews are working as painters on a new housing estate. Mitcham, the younger of the men, has served two short terms of imprisonment. Andrews, from the Midlands, is a more experienced criminal. They have planned a job together. As it will be Mitcham's first attempt at big-time crime they require a third man. Mitcham, anxious to ingratiate himself, says he knows someone. When the job has been pulled PC Quilley finds a source of information. ""It's teamwork that gets results,"" says Sgt. Stone. Why, then, is the job taken out of Quilley's hands?
