The Doctor, Clara and some Redshirts decide to Fantastic Voyage into the seemingly only good Dalek in existence
Human resistance forces have injured and captured the only good Dalek known to have ever existed, and are now in need of a Doctor with an eye for the most minute detail. Rescuing young soldier, Journey Blue, from the universe-subjugating lasers of the Daleks, The Twelfth Doctor is inexplicably drawn into the fight.
Meanwhile, at a completely different point in time and space, Clara is flirting with socially awkward, PTSD-ridden fellow teacher, Danny Pink, when she saunters into a cupboard and is recruited by the Doctor to join the mission.
What’s the mission? Glad you asked. Alongside Journey Blue and two redshirts, Doc and Clara are shrunken down to about an inch in height, in order to Fantastic Voyage into the dark depths of the good Dalek, to heal it — and perhaps all Daleks — from within.
