Beachhead · Doom Coalition 2 • Episode 1

In an attempt to recharge his batteries after his confrontation with the Eleven, the Doctor takes Liv and Helen to the sleepy English seaside village of Stegmoor. But they find the village in turmoil and, to make matters worse, their arrival uncovers a mystery from the Doctor's past which threatens the future safety of the planet. Can the Doctor prevent the Voord from invading Earth? And more importantly why have they come in the first place?

There are some really tense moments in this story thanks to characters going way further and darker than I would have expected them to do. Really kept me on edge. The gunpoint scene was outstanding.
