The team from an underwater base in a lake bring an alien spaceship on board. It all seems safe enough until the ghosts appear. The Doctor and Clara arrive to find the crew living in fear and the TARDIS takes a strong dislike to being there. The ghosts slowly figure out how to manipulate the base to their advantage as they apparently seek to kill everyone - but for what purpose?

The Doctor, while originally opposed to the idea of ghosts, eventually comes round and is positively excited about the prospect. As he tries to figure out what's going on, we see that the ghosts have a purpose and are apparently speaking the same set of words over and over. The Doctor determines these are coordinates and match the words on the inside of the ship (which, oddly, are not translated by the TARDIS). The ultimate purpose seems to be to send a signal to bring other aliens here.

The Doctor, Clara and the crew eventually trap the ghosts (with a clever use of the new sonic sunglasses) but they fight back by letting water into the base. As everyone heads for the TARDIS, Clara and two crew are trapped. The Doctor heads off with the others, saying he will go back to before the dam burst to create the lake, and find out what's going on and prevent this from happening.

Then comes the cliff-hanger, Clara and the remaining crew spot a new ghost. It's the Doctor! What happened in the past?
