The TARDIS lands on the surface of the sea, just off the east coast of England. The time travellers use a rubber dinghy to get ashore, where they are shot with tranquilliser darts and taken prisoner by security guards as they have arrived in the restricted area of the Euro Sea Gas refinery.
At the refinery base, run by a man named Robson, the Second Doctor learns that there have been a number of unexplained problems with the pressure in the feed pipes from the offshore drilling rigs and a strange sound is reverberating through the pipeline. 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.
