The Sea Devils was the third story in the ninth season of Doctor Who. It marked the first appearance of the Sea Devils and the reappearance of the Master.

Barry Letts and Terrance Dicks had decided they wanted a sea-based story and asked Malcolm Hulke to write it. Instead of bringing back the Silurians, Hulke invented an aquatic version called the Sea Silurians. Unlike their counterparts, the Sea Devils were given clothing designed by Maggie Fletcher.

To answer the insistence by fans that the Silurian era could not have spawned man-sized life, Hulke introduced a line in which the Doctor says they should correctly be called Eocenes. However, some considered it also unlikely that the Eocene period could produce such life.

After appearing in all five stories of season 8, Letts had decided to restrict the Master to a few appearances each year. This story joins him where The Dæmons left off, with his imprisonment. The dialogue implied that the Doctor and the Master were once friends.

Letts had secured the involvement of the Royal Air Force for The Mind of Evil and decided to try to do the same with the Royal Navy. He found the Ministry of Defence eager to take part. Shortly after broadcast, the BBC was visited by officials from the MOD who believed their top-secret submarine had been used in the show. It was in fact a model, adapted to show the features they were secretly testing.

This story saw the only use of "reverse the polarity of the neutron flow", during the Pertwee era. The phrase became associated with the Third Doctor, so he used it again in The Five Doctors, some eleven years later. Pertwee did use a shortened version of the phrase, "reverse the polarity", several times.

Like many of Hulke's stories, it included a moral dimension. The Sea Devils are caught between the Master, the Doctor and the humans. Ultimately, they are betrayed by all three; like their land-based cousins, it is the humans who hurt them the most.

Synopsis

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

Plot

Episode one

The Doctor and Jo visit the Master in his cell.

The Doctor and Jo visit the Master, now a captive on a small island prison after being captured by UNIT.

The Master is being held indefinitely and is the only prisoner. He is watched by CCTV and the island is patrolled by armed guards – trained to resist the Master's hypnotic powers – and even protected by minefields. He claims to have reformed – but refuses to reveal the location of his TARDIS. As they depart, the old-school, patriotic governor, Colonel Trenchard, tells them that some ships have been disappearing mysteriously. Shortly afterwards, he visits the Master, and it becomes clear that they are in league.

The Doctor cannot resist investigating, so they visit the nearby naval base, HMS Seaspite, run by the efficient Captain John Hart; despite the Doctor's eccentric behaviour - he claims to have known Nelson personally - an alliance forms. The Doctor states that that the linear scorch pattern was caused by a concentrated beam of heat from under the sea. Hart is in charge of the adaptation of the sea fort to a SONAR testing station. The Doctor and Jo make their way to the sea fort. Jo and he are soon attacked by a Silurian lookalike.

Episode two

A Sea Devil is discovered by the Doctor.

It is not a Sea Devil, but a half-mad crew member ranting about them The Doctor and Jo decided to calm him down. They find that the radio was ripped out. The Doctor decides to go get a transistor radio in order to turn it into a transmitter.On bis way, he encounters a hostile Sea Devil, who fires at him. When it tries to break in, it is hurt and flees. Shortly afterwards, the Doctor finishes his transmitter, and they are rescued.

John Hart decides to find them after they had seemingly disappeared. The Doctor and Jo attempt to get Hart to tell a higher authority. His assistant gets a call fdom someone ranting about Sea Devils. The Master comes to HMS Seaspite to steal some equipment. Colonel Trenchard follows, providing a distraction. Jo still sees him leaving.

The Doctor and Jo confront Trenchard, and he tries to dissuade them by showing that he is "still" in his cell. The The Master knocks out a guard and grabs his knife. Trenchard then gets the Doctor to go see the Master, who attempts to kill him, first with gun and then with sword. The Master then throws the dagger at the Doctor's back....

Episode three

The Master working in his cell.

The Doctor survives. Trenchard decides to lock the Doctor in the prison and attempts to capture Jo. The evil Time Lord tells him that he intends to use the reptiles as an army to conquer the planet. It is revealed that the reason Trenchard is helping the Master because he believes they are fighting enemy agents. Meanwhile, Jo comes and frees the Doctor. He begins by using the machine to summon some of them from the sea – forcing the Doctor to employ his sonic screwdriver to repel them by exploding mines on the beach.

Episode four

The Sea Devils attack the submarine.

While the Docotr and Jo navigate through a mine field, a Sea Devil attacks another submarine. rThe Doctor and Jo flee to HMS Seaspite, where Hart tells them another naval submarine has disappeared.

Meanwhile, the Master returns to his cell to begin work on a new device. He activates it and it calls the Sea Devils to him. They attack the prison, killing the guards and Trenchard. A battle for the prison rages. Trenchard, who believed he was aiding his country against enemy agents, is killed.

HMS Seaspite heads out of investigate a section of seabed. The Doctor goes down in a diving bell. When theycall back him up, he refuse,and the diving bell is lifted by force. It is empty....

Episode five

The Master and Sea Devils converse.

The Sea Devils take the Doctor to their leader. The Doctor enters the Sea Devils' base and tries to encourage peaceful negotiation, recalling how he had failed to broker an agreement between mankind and the Silurians. The Master arrives to incite matters by trying to provoke war.

Walker arrives to "solve" the sinking ship problem by dropping depth charges. Meanwhile, the Doctor has gained the upper side of the argument. The depth charges disrupt the negotiations. The Master convinces the Sea Devils to take him away and kill him. He also convinces them to attack on of their bases. The Doctor has freed two of the submarine crews and then rescue the others. They try to leave, but the Sea Devils hold them back. They fire torpedoes to provide thrust and escape.

The Doctor confronts Walker about his depth charges, which have just made the Sea Devils angry. The Sea Devils rise and attack the HMS Seaspite. As the Doctor attempts to go down to negotiate again, a Sea Devil raises its gun at them....

Episode six

The Doctor fights the Sea Devil off with Venusian karate, but another captures him. The rest of the Sea Devils captures the rest of the people at the base. The Master tells the Doctor that he needs help to complete his machine so he can revive the colonies all over the world.

Meanwhile, Jo and escapes through a ventilation shaft. Jo reaches the Doctor and he tell her that he will deal with the guards. The Doctor makes the machine emit a shrill noise which puts the Sea Devils in agony. John escapes with Jo. The Master shuts the machine, and the Sea Devils, the Doctor and the Master head back to the Sea Devil base.

This prisoners retake the base. A soldier arrives to keep watch over the Master, but the Master hypnotises him, and he escapes. The Doctor chases after the Master, and they reach the base, where multiple Sea Devils capture them. Meanwhile, Walter orders a nuclear strike. The Doctor sabotages the machine, and the Time Lords are imprisoned. The Doctor reveals that he reversed the polarity of neutron flow, which will cause a massive explosion. The Time Lords escape the usage of the Doctor's sonic screwdriver and of an aiirlock. They rise to the surface and are rescued.

Story notes

• This story had the working title The Sea Silurians.
• The scene involving the Master watching Clangers was a last-minute addition, added because the first episode was missing ninety seconds of the standard run time.
• This is one of two stories where the Third Doctor utters the full line, "I reversed the polarity of the neutron flow". The other is in TV: The Five Doctors.
• The Sea Devils are never named as such (except the fort survivor rambling about sea devils).
• The Doctor remarks that he was a personal friend of Horatio Nelson.
• This serial's director, Michael Briant, provided the voice of the radio DJ in episode two.
• Originally, episode one was to include the Doctor water-skiing, which was to be used as the excuse for Jo and him being late to the Master's prison. Increasingly inclement weather made the shoot impossible.
• Along with Mission to the Unknown, Doctor Who and the Silurians, The Mind of Evil, The Dæmons, The Sontaran Experiment, Genesis of the Daleks, Remembrance of the Daleks, and Midnight, this is one of only nine televised stories in the history of Doctor Who not to feature the TARDIS (The Ambassadors of Death, Inferno and Day of the Daleks feature the central console, but not the TARDIS itself).
• The series' producer, Barry Letts, and Clive Morton (George Trenchard) had both previously appeared in the 1948 film Scott of the Antarctic in which they played Apsley Cherry-Garrard and Herbert Ponting respectively.
• Donald Sumpter (Commander Ridgeway) previously played Enrico Casali in TV: The Wheel in Space and would later play Erasmus Darkening in TV: The Eternity Trap.

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.) Delgado also looks very uncomfortable during his scenes in the water.

Filming locations

• The exterior of the Master's prison was in fact Norris Castle, East Cowes, Isle of Wight. The Sea Fort was an actual sea defence fort built in the 1860s in the river Solent, off the South Hampshire coast, in anticipation of a feared French invasion which never came to pass. Abandoned at the time of the story's filming, it has since been 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.
• Fraser Gunnery Range, HMS St George, Portsmouth
• Royal Navy ship HMS Reclaim
• No Man's Land Sea Fort, Solent
• Whitecliff Bay, Isle of Wight
• Bembridge Harbour, Isle of Wight
• Norris Castle, East Cowes, Isle of Wight
• Red Cliff, Sandown, Isle of Wight
• Bembridge Sailing Club, Bembridge, Isle of Wight
• Priory Bay, Isle of Wight
• BBC Television Centre (Studio 8), Shepherd's Bush, London
• The set for the Wardens office is the same one heavily used for the Doctors laboratory in the previous season.
