Early access of the full season begins Monday, March 15 on AMC+

Missing from the BBC Archives, this animated version of the 1968 classic sees the TARDIS land on the surface of the sea, just off the coast of England. The Doctor (Patrick Troughton, The Omen), along with his companions, Jamie (Frazer Hines, Two Days in the Smoke) and Victoria (Deborah Watling, The Invisible Man) use a rubber dinghy to get ashore, where they are shot with tranquilizer darts and taken prisoner by security guards as they have arrived in the restricted area of a gas refinery.

At the refinery base, run by a man named Robson (Victor Maddern, Chitty Chitty Bang Bang), the Doctor learns that there have been a number of unexplained problems with the pressure in the feed pipes from the offshore drilling rigs. It is later revealed that one of the rigs has sucked up a parasitic form of seaweed, which is capable of releasing poisonous gas or a strange kind of foam that allows it to take control of the minds of those it touches.
