Professor Keller (Simon Lack) has created a machine that can pacify even the most dangerous of criminals. But when the Doctor (Jon Pertwee) and Jo (Katy Manning) arrive at Stangmoor Prison for a demonstration, things start to go horribly wrong - especially when they discover that the Doctor's old enemy the Master (Roger Delgado) is responsible for the machine. What could he possibly want from the criminals? And what connects him with an impending World Peace Conference?
