Series from 1969
UNIT, and Benton, is introduced and we meet the Time Lords and finally learn something of the Doctor’s past, saying goodbye to Jamie, Zoe and the Seco…
The TARDIS arrives in no man’s land during World War I. Rescued from the Germans, the travellers are put on trial by the British General Smythe who is not all he seems.
Finding evidence of alien technology in Smythe’s office, the Doctor, Jamie, and Zoe make their escape in Lady Jennifer’s ambulance, but Smythe gives orders to have them killed.
The Doctor discovers that they are on an alien planet divided into different time zones where human soldiers fight never-ending wars.
The Doctor and Zoe penetrate the Aliens' HQ from where the war games are controlled. Carstairs is reconditioned and exposes the Doctor and Zoe as German spies.
In the American Civil War zone, Jamie and Lady Jennifer join forces with resistance fighters from various time zones and prepare to launch an attack on Central Control.
The Doctor sends Zoe to the war zones to assemble a resistance force. The Doctor remains in Central Control to steal the processing machine, but the War Chief is one step ahead.
