And find themselves facing a deadly foe from the afterlife.

Story notes

 * Sergeant Quick and Doctor Tulp do not appear in this story as producer, David Richardson, wanted to focus more on the character of Ellie. As a result this story is not directed by Lisa Bowerman but by John Ainsworth.
 * Janet Henfrey (Mrs Vanguard) previously played Miss Hardaker in TV: The Curse of Fenric.

Continuity

 * Numerous references are made to the events of AUDIO: The Bloodless Soldier.
 * Jago refers to Li H'sen Chang's act at the Palace Theatre. (TV: The Talons of Weng-Chiang)
 * An attempt by time travelling humans from the far future to take over the bodies of their ancestors with the intention of altering their own history also occurred in Russia in the late 21st century. Their plan was defeated by the Fifth Doctor and his companion Turlough. Notably, on that occasion, the Doctor told Turlough that he had witnessed World War V in the 49th century, suggesting that this may have been the conflict from which the refugees were fleeing. (AUDIO: Singularity)
 * Mr Jago compares the possessed bodies to a Doppelgänger, a word used to describe the Fourth Doctor's double in  Meglos and the flesh-made doubles at St John's Monastery in  The Rebel Flesh/ The Almost People.
