Video of the Day – Doctor Who: The War Games, 1969

The TARDIS materialises in what appears to be a no-man's-land on a World War I battlefront in France. When the Doctor, Jamie and Zoe emerge from a cloud of mist into another period of time, they realise that they are in fact on an entirely different planet that has been split into different time zones - where a fierce war is being waged in each one.
