UUU. The Time Warrior
During the medieval times a space craft crash lands. When the locals go to visit what they thought was a star falling, they find an armoured soldier. When questioned the soldier finds that the locals have no technology that can aid him, and he must seek those who have.
In the twentieth century U.N.I.T. are called in to investigate a case of disappearing scientists. Also present is an journalist, Sarah Jane Smith, posing as Lavinia Smith, her aunt. Whilst the Doctor is there another scientist disappears, and the Doctor sees the ghostly image of a Sontaran warrior.
The Doctor follows the Sontaran back to the medieval times, with Sarah as a stowaway. There he finds the Sontaran, Lynx, has been helping Irongron by providing breach-loading weapons in return for a place to repair his craft which was damaged in their war with the Rutans.
Lynx has been using a primitive device to kidnap scientists from the twentieth century to repair his craft. with the aid of a local archer Lynx is killed by an arrow jammed in his probic vent during take off. The ship explodes, taking the castle with it. Before this happens the Doctor manages to return the scientists to the twentieth century, and get all of Irongron's people out.

Sarah is put to work peeling potatoes in the 12th century. (Potatoes were not introduced to Europe until Elizabethan times.)
Episode 1 : When Linx first meets Irongron and plants his flag (claiming Earth for the Sontaran Empire), immediately before the scene change, and for no apparent reason, Irongron and Bloodaxe both turn their heads and look away from Lynx, off stage to their right.
This story marks the first use of a new title sequence, designed by Bernard Lodge (who is now credited for the first time); the fourth one used for the series.
