Oh good. It’s another Doctor Who DVD! This one was first shown in 1977, and stars Tom Baker as the Doctor, and Louise Jameson as Leela.
The story was inspired by the poem Flannan Isle by Wilfrid Wilson Gibson, which I remember studying in school. It’s set on a lighthouse, a perfectly isolated location for the events that unfold. One by one, the crew of the lighthouse and the survivors of a shipwreck are killed. The generator powering the light keeps failing. What is going on? Can there be a connection between the deaths and the strange light that one of the crew saw falling into the sea?
As ever, the Doctor identifies the source of the trouble, and arrives at a solution - too late for the people in the lighthouse, but in time to save Earth from invasion or destruction.
There’s the usual generous selection of extras - the now-standard production subtitles, a look at some of the huge range of Doctor Who merchandise and a couple of documentaries.
