In Anterctica, nearly fifty years after the end of World War 2, Nazi Initiates inhibit a secret base; around them move the shadows and reflections of strange, Imp-like figures... The village of Turelhampton in Dorset is still a restricted military zone, cordoned off from the outside world. When a rogue film-crew breaks in, welrd damons, invisible to the naked eye, appear on camers... And in a remote country-house in Cornwall, a freelance investigative journalist is horrified to discover neo-Nazis performing an occult ritual involving a functional, accurate, crystal ball - the Scrying Glass. And in the background, the figure of Hilter watching, exactly as he appears in the last pictures of him alive... What really did happen in the Berlin bunker in 1945, when Hitler and Eva Braun supposedly committed joint suicide? And what connection does this have with the uncanny imps that can be seen only in reflections and shadows? Why is it so imperative that no-one discover the secret of Turelhampton? It is up to the Doctor and the faithful Brigadier to find out.
