What Season 12 of Doctor Who

The season opens with the Doctor freshly regenerated and still weakened, when a massive force steals a secret weapon.

Then the story moves to Nerva Space Station, where the Doctor, Sarah Jane and Harry face the Wirrn, the Sontaran experiments and Davros's plans on Skaro. The Cybermen return on Voga, a moon of Jupiter where a space plague threatens the satellite. The episodes are interconnected and form a shared story arc centered on the station.
