Just released from prison, reformed cat-burglar Spider Scott is determined to stay on the straight and narrow this time. Unfortunately for Spider his body is working against him - he has an abnormal genetic predisposition towards crimes against property and there are a number of factions willing to take advantage of his skills, including the British Government. Carrying out sanctioned burglaries is more dangerous than normal kind, as Spider soon finds out, and it's not long before he is hotly pursued by Detective Sergeant Bulman. A cult success when it was first shown in the 1970s, the XYY Man was a strong combination of both the crime and spy genres, with a compelling central performance by Stephen Yardley as cat-burglar Spider Scott. The XYY Man span off into the extraordinarily successful Strangers , which moved the quirky copper George Bulman to centre stage.
