Doctor Who: The Twelfth Doctor: Beneath the Waves: Part 3

The Doctor's attempt at a relaxing trip to the seaside took a somewhat unexpected turn, when the town was invaded by seaweed husk creatures. With the help of Hattie and a team of angry pensioners, the Doctor managed to temporarily hold off the monsters, but their psychic attacks are paralyzing the citizens of the sleepy town. The Doctor is determined to get answers, even if that means putting himself on the front line… or beneath the waves!
