Simon Templar, aka The Saint, helps those whom the conventional agencies are powerless or unwilling to protect. His methods often skirt the law which often brings him into contact with Chief Inspector Claud Eustace Teal who believes that Templar is little more than a common criminal, though he often begrudgingly tolerates Templar's actions for the greater good.

In this episode, "Escape Route," Templar stages a jewelry robbery and is sentenced to ten years in a Dartmoor prison where he befriends a fellow inmate, John Wood, who has links to a gang arranging prison escapes.
