Plot
After their adventures in India, the Doctor and Clara return to her present – but danger is slipping through the cracks between universes, and London (and UNIT!) have no defence against the Fractures! Will the Doctor risk all of reality to reunite a family – or sacrifice a good man to keep the multiverse spinning? • Then, the Doctor gambles with his life in 1960s Las Vegas, as he and Clara must team up with gangsters in order to defeat an intergalactic crime syndicate – but is this one too many spins on the Doctor's roulette wheel?
