The Doctor revisited a previous adventure, where an entire town had been turned into zombie-like shells of their former selves, under the terrifying influence of a giant smile in the sky! Another enemy was defeated, with the help of the few unaffected locals – and a very brave, very lonely little boy. Now the Doctor must return his thoughts to a more pressing problem… the seaweed husk creatures attacking him and Hattie in a sleepy British seaside town! While a husk grapples with the Doctor, Hattie is pained by a psychic attack!
