The Five Doctors: Someone is taking the Doctor's past selves out of time and space, placing them in a vast wilderness, a battle arena with a sinister tower at its center.
As the various incarnations of the Doctor join forces, they learn they are in the Death Zone on their home world of Gallifrey, fighting Daleks, Cybermen, Yeti...and a devious Time Lord Traitor who is using the Doctor and his companions to discover the ancient secrets of Rassilon, the first and most powerful ruler of Gallifrey.
Starring Peter Davison, Jon Pertwee & Patrick Troughton with Richard Hurndall, Tom Baker and William Hartnell.
The King's Demons: It is thirteenth century England, and King John is visiting the castle stronghold of Sir Ranulf Fitzwilliam. Ranulf's personal fortune has dwindled away, freely donated to King John to help fund the Crusade. While staying with Ranulf, the King's greed is criticized by the baron's head-strong son, Hugh. As a result, Hugh is challenged to a duel by the monarch's French Knight-at-Arms, Sir Giles Estram, a duel the young Englishman has little hope of surviving.
When the TARDIS materializes and disturbs the joust, the Doctor's party are proclaimed friendly demons by the King, who seems stragely interested in their "blue engine". Before long the Doctor becomes embroiled in court politics, and he realizes that there is far more to the situation than a simple battle of honor between nobles. Starring Peter Davison
