Michael Portillo unlocks the doors to four extraordinary abandoned locations.

In 1943, the village of Imber in Wiltshire's Salisbury Plain began to be used as a Second World War training ground. At risk from friendly fire, each household was ordered by the War Office to abandon its home for the duration of the conflict. Despite promises that the residents could return after the war, the village remains in the hands of the military, and has been since used for training against the IRA and the Taliban. Michael meets former residents and relatives to hear this story of upheaval, and talks to historians to reveal the history behind the desolation of this ancient village.
