Peter Capaldi has now occupied the TARDIS for two seasons but while he’s redecorated, he’s been travelling with Jenna Coleman’s Clara, who still somehow felt like she worked far better in Matt Smith’s era.
The Doctor and Clara arrive on an underwater base in the 22nd Century. They find surviving crew haunted by ghosts with murderous intent with the apparitions apparently caused by mysterious alien spaceship.
The Doctor is trapped on Skaro, planet of the Daleks, and is forced to face Davros one last time. Meanwhile, Clara and Missy must put their differences aside in order to mount a rescue through the Dalek sewers.
