Off the coast of Wales outside the village of Ynys Du, the disused lighthouse appears to have some business going on. And in the village, things aren't much better. So when the Doctor and Rose arrive to monsters in the woods, the Doctor's determined to find out what's going on and put a stop to it.
This story features the Tenth Doctor (as played by David Tennant) and his companion Rose (played by Billie Piper). The story is a good blend of monsters-under-the-bed, haunted rectories, aliens and old village secrets. The Doctor and Rose are pulled into the middle of a mystery that they unwittingly become part of. The action is well-paced, and the characters are well drawn. All round good Doctor Who story.
