Savage and Silk were sent to rescue an engineer from Dartmoor maximum security complex. Making contact with him in a quarry work party, he was reluctant to try to escape. Returning to their transport they found a local farmer working for the resistance dead and the range rover damaged as wild dogs which had been experimented on found their scent.
Savage freewheeled the damaged car downhill into a swamp. The dogs still followed them through the swamp and Savage realised a seam of dried blood was sewn into every prison uniform. The professor stripped and Savage threw his uniform onto a Volgan hovercraft, shooting out the skirt so that the dogs turned on the Volgans.
