STORY PLOTLINE
The TARDIS arrives on a planet where a race known only as the Aliens have gathered soldiers from a number of different wars in Earth's history, brainwashed them and put them to battle. Their aim is to form an invincible army from the survivors and use this to take over the galaxy.
The War Lord is assisted by a Security Chief and a War Chief, the latter of whom the Doctor quickly recognises as a member of his own race, the Time Lords.
