After space babies and The Beatles, the third episode in the new Doctor Who series starts with two soldiers are navigating their way through a battlefield shrouded in fog. One is talking on the phone to his daughter. “Kiss kiss,” he says as he signs off. A bad sign, right?
Indeed, a few minutes later, they’ve disappeared, the Doctor arrives, and the episode kicks off properly when he lands himself in a spot of bother by stepping on a landmine. For the rest of the episode, he’s stuck there, while his companion Ruby attempts to save him. Until things go wrong, which of course, they do.
