The Sea Devils (TV story)

"There are thousands of us in hibernation in this place. We have colonies hidden all round the world. We will be avengers in the war against Man."

- The Chief Sea Devil

Synopsis
The Doctor and Jo visit the Master in his high-security prison on an island off the south coast of England and hear from the governor, Colonel Trenchard, that ships have been mysteriously disappearing at sea.

Investigating, the Doctor learns from Captain Hart, commander of a nearby Naval base, that the sinkings have centred around an abandoned sea fort. He and Jo then visit the fort and are attacked by what one of the men there terms a Sea Devil - an amphibious breed of the prehistoric creatures encountered by the Doctor shortly after his exile to Earth.

The Master, aided by a misguided Trenchard, is stealing equipment from the Naval base in order to build a machine to revive the Sea Devils from hibernation.

The Doctor takes a diving bell down to the Sea Devils' underwater base to try to encourage peace. His efforts are frustrated by a depth charge attack ordered by a pompous politician, Walker, but in the confusion he manages to free a captured submarine and escape back to the surface.

The Sea Devils then capture the Naval base, and the Master has the Doctor taken back to their control centre, where he forces him to help finish the machine. The Doctor sabotages the machine and the two Time Lords escape together just as the base is destroyed in an explosion.

Myths

 * Roger Delgado was afraid of the water and it took great courage for him to film the scene in which the Master and the Doctor are rescued from the sea by the Navy. (This was frequently recalled by Jon Pertwee in later interviews, but according to Delgado's widow Kismet it is untrue. Delgado was actually worried about getting his costume wet, as there was no spare available.) (Delgado's fear of water is also recalled during the DVD commentary of The Sea Devils by Barry Letts and Terrance Dicks)

Filming Locations

 * The exterior of the Master's prison was an actual sea defence fort, the Solent, built in the 1860s off the coast in anticipationhttp://tardis.wikia.com/index.php?title=The_Sea_Devils&action=edit of a feared French invasion which never came to pass. Abandoned at the time of the story's filming, it has since become a hotel resort. In July of 2007 the fort came up for sale after the company owning the hotel collapsed and its owner was jailed.
