It saw the series revisit the concept of ghosts and hauntings, last explored in the television story Hide. The episode poses another explanation for the apparitions, in this case as resurrected transmitters of an alien presence's signal.
It also continued the thematic concept of the Doctor apparently facing death, with the end of the episode setting up yet another opportunity for the Doctor to reflect on his mortality.
Arriving on an underwater base under attack, it's up to the Doctor and Clara to save the frightened crew. But also onboard is an alien spaceship, and the base is being haunted by the most impossible of things.
The Doctor's deepest beliefs are challenged when he encounters something he cannot explain. Can it really be possible? Can ghosts be real?
In an underwater mining facility based in Scotland, 2119 designated The Drum, the captain, Moran, is recording a log in his journal. Moran states that the team has discovered a small craft located on the bank, and, as they are unable to analyse it from within the base, they have brought it inside, where he and the crew will investigate.
A crew member named Lunn interprets the sign language of another crew member, Cass, saying that the reason for its sudden appearance is due to underwater movement and shifts on the floor of the lake. Another crew member named Pritchard recommends they discuss ownership the spaceship, prompting Moran to tell everybody to stop calling it a spaceship, as they don't know what it is.
The crew enter, and Moran notices something inside the craft, asking Lunn to hand him a torch. Lunn does so, but glimpses a ghostly figure reflected in the glass. He reluctantly hands Moran the torch. Moran investigates four strange markings on the wall, whilst Lunn asks Cass why he shouldn't go inside. Whilst they bicker, Pritchard cries out as he glimpses the ghost, accidentally starting the engines. Moran pushes Cass out of the way of the boosters' range, but is struck by the blast, forcing the crew to retreat, leaving him behind.
O'Donnell, another crew member, bangs on the sealed door, demanding they go back for Moran, but is told it is impossible by the rest of the crew. She yells at Pritchard for messing with the controls, but is interrupted as Cass screams. She turns, startled to see a ghostly Moran, with gaping back holes for eyes hovering in front of her. The same figure, named Albar Prentis appears, and the pair reach out to the crew...
3 days later, the facility is a wreck, being seemingly empty. The TARDIS appears, with Clara, and the Doctor stepping out, with him realizing that they are in the 22nd century. Going to the mess hall, they see that it has evidence of a fight with a knife stuck in a wall. The Doctor realizes that that took place very recently. In a corridor, they see the figures who simply examine them and leave.
In the hangar the Doctor and Clara find the spaceship and see the markings, which the TARDIS is unable to translate. The ghosts pick up axes and harpoons and attack them. They flee but the ghost follow them, albeit having to leave their weapons behind.
