Danger Man S02E03 - Colony Three

Drake takes the place of a defector and goes behind the iron curtain to find out what is happening when foreign agents reach England. When he gets there he finds a replica English village, which is a school where foreign agents are taught to 'be British'. Actual British subjects, such as Drake, are employed to teach the agents the finer points of the British way of life. Drake sets out to disrupt their education and stop the supply of agents from reaching England.
