In 1990 Agent Fox Mulder visits an aging FBI Agent named Arthur Dales. He listens to a story of the agents assigned to a would-be X-File in the Cold War era of the 1950's and how Mulder's father was connected to a series of strange deaths.

Arthur Dales summons Mulder and Scully to his holiday home in Florida where he is concerned over the disappearance of his neighbors. Despite the raging hurricane, Mulder and Scully head out to investigate and discover several strange deaths caused by an octopus-like sea creature that swam in through the overflowing sewer system.
