The Doctor and Donna arrive in a huge abandoned library, along with a team of archaeologists. But something in the shadows is stalking them...

I'm getting a vibe from this trailer that tells me this story seems like the kind you would have had in the New Adventures novels of the 90s. Abaondoned place, some deadly ancient secret, a team of scientists/soldiers... heh, classic New Adventures formula, which is not a bad thing at all.

I just wish I didn't have to wait TWO WEEKS for it! D:
