The Doctor and Donna are taking a bit of a break from their adventures and spending a bit of time on the planet Midnight. While Donna opts to spend a bit of time in the spa, the Doctor goes off on an all-day bus tour to the Sapphire Waterfall. Part way through the four hour journey to get there, the vehicle stops for no apparent reason. When they hear noise coming from outside the vehicle, panic begins to set in. When one of the passengers is taken over by the being, the passengers paranoia and fear know no bounds and the focus of their solution is to eliminate the Doctor. Written by garykmcd

One of the best!
15 December 2009 | by Meimi132See all my reviews

Seriously, ignore carrotjuicer3000's review. This is one of the best episodes of season 4, maybe of the whole series. It's suspenseful, its well written, its just....eerie. Just because its a standalone episode doesn't mean its not just as good as others. And not every episode needs comic relief, specially not one like this. So Tate is not missed. She gets the next few episodes focused on her anyways.

Lesley Sharp is fantastic in her role, marvellously creepy... Tennant is brilliant as always. The supporting cast is fantastic too, which includes Colin Morgan(Merlin).

Once you start watching this episode, you literally can't stop. Every time I've seen it repeated on BBC3, and skipped over the channel, at any point during the episode, I'd have to continue watching. Who'd a thunk an episode set in one room would be so brilliant? It's simply....molto bene.
