Main subject Edit
A small part of the fourth episode of the story, "Checkmate", is still missing — namely, from the scene where the Saxons, led by Wulnoth, surround and kill the Vikings, Ulf and Sven. This short item uses an off-air audio recording and an original script to place the missing twelve seconds in context.
Home video releases Edit
This documentary was included on the DVD release of the Doctor Who story The Time Meddler.
