The Sensorites (TV story)

The Sensorites was the seventh story of the first season of Doctor Who. Though The Keys of Marinus and The Daleks had both been clear examples of science fictional Doctor Who adventures, neither had specifically stated they were in the relative future of the series. By contrast, The Sensorites was the first story to flatly state a setting in advance of the century of broadcast.

The third episode, "Hidden Danger", had the dubious distinction of being the first episode of Doctor Who delayed because of programming from another BBC department. Just as most series of the BBC Wales version have featured a one-week gap for Eurovision, The Sensorites was interrupted for special sports programming. (REF: The First Doctor Handbook)

Narratively, certain elements of the story carried on into 21st century Doctor Who. Susan's description of her home planet was almost directly quoted by the tenth Doctor in Gridlock, and Planet of the Ood suggested a genetic kinship between the Ood and the equally telepathic Sensorites.

Summary
The Doctor, Ian, Barbara and Susan arrive in the TARDIS on board a spaceship. Their initial concern is for the ship's human crew who are suffering from telepathic interference from the Sensorites, but Susan communicates with the Sensorites and finds that the aliens are fearful of an attack from the humans and are just defending themselves. Travelling to the Sense Sphere (the Sensorites' planet) the Doctor then seeks to cure an illness the Sensorites and Ian have succumbed to, but finds that this has been caused by deliberate poisoning. The political maneuvering of the Sensorite City Administrator adds an additional threat to the TARDIS crew as he seeks to discredit and implicate them.

Strangers in Space (1)
The TARDIS travellers find they have landed on a drifting spaceship and find the crew dead. As they inspect the bodies, they find that they are warm, even though their self-winding watches (which are powered by the movement of the wrist) say they have been dead for at least 24 hours. As the travellers go to leave, one of the crew members, Captain Maitland, regains consciousness and Ian Chesterton helps revive him using a device that he later calls a heart resussitator. They use this device on the other crew member, Carol Richmond. These two tell the travellers that they are on an exploration mission from 28th century Earth and are orbiting Sense-Sphere. However, its inhabitants, the Sensorites, refuse to let them leave the orbit as they are able to control the brains of any human around them. They go on to say that The Sensorites put them to sleep but never kill them, in fact they regually feed them whilst they are in these states to keep them alive.

As they are leaving they do not notice that a mysterious figure is burning the lock out of the TARDIS. As Ian starts to question Maitland on the future of Earth, the Doctor decides that they should leave for fear that Ian learns too much. It is then they discover that the lock is missing which means that the TARDIS is permanently locked.

As they come to terms with the fact that they are trapped, the Sensorites send the Earth ship on a collision course into the Sense-Sphere by taking over the minds of the two pilots and forcing them towards the planet. The Doctor manages to divert this because he and his travellers seem to be immune from the Sensorites power. Carol states that they have found that different people are affected in different ways. She speaks of another crew member named John who was affected more. When Maitland is questioned about John he says he'd rather not talk about it.

Later that day Barbara and Susan are making food for the rest of the crew and ask Carol where they can find some water. Misunderstanding the directions they go through a sensor operated door. As they go through, an unknown man, seemingly John, locks them in with him inside. John appears to be in a zombified state and begins to shuffle towards the frightened girls. However when he finally has them cornered he collapses in front of them and weeps. Barbara consoles him and says that she will make sure he gets better.

Meanwhile on the outside of the door the rest of the crew realise that Barbara and Susan are stuck inside the lock with John. Maitland begins to use a cutting device to get them out. While this is happening Carol confides to Ian that John was to be married to her when they returned to Earth. As the cutting goes on Maitland here's a noise. It is an approaching Sensorite ship. The crew prepare themselves at the controls as the ships roam into sight. Eventually the ship is surronded and Ian is astounded to see a Sensorite at the window.

The Unwilling Warriors (2)
The Sensorite at the window renders Carol and Maitland entirely incapable of movement. Eventually the doctor awakend Maitland and reminds him of Susan and Barbrara trapped on the other side of the door. Maitland continues to cut them out. In the locked area Barbara and Susan are comforting John who is still visibly distressed. He appears to be in semi-constant communication with the Sensorites who are trying to convince him to sare away the travellers. Something he refuses to do as they are his friends now. This act of defiance leaves him crumpled up in pain on the floor.

Whilst this is going on two Sensorite elders have entered the ship. John senses this and informs his new friends. Barbara mentions to susan that sheonce visted a planet named Esto on which their lived a species of telepathic plants that screeched when you stood between them as you affected their thought pattern. With this in mind Barbara and Susan try and overpower the Sensorites thought patterns by both focusing on the phrase "We Defy You" at the same time. This seems to strongly effect the Sensorites who crumple to the floor.

Ian and the rest of the team manage to open the door and release Barbara, Susan and the unconcious John. Whilst Ian is putting John to bed he mentions the phrase "the riches of avarice." Ian shares a theory that John discovered something about the Sense Sphere that would prove valuable to the human race which is why they have trapped the vessel. This is backed up when Maitland states that John was the ship's mineralogist. A quick glance at his findings confirms to the Doctor that the Sense Sphere is rich in Molybdenum, a very precious material. As the Doctor makes this discovery the Sensorites mentally attack Carol and Maitland again. Barbara and Ian go and look for the Sensorites and eventually find them. Barbara runs back to the crew to ask how to lock the doors in an effort to imprison them whilst Ian slowly backs up, threatening them with a hammer he's found.

Barbara has to wake John to lock them in a supplies closet. Barbara notes that they were reasonably passive and never tried to harm Ian. As Barbara and Ian go back to the others to discuss what to do with their prisoners, the Sensorites use adevice to escape. Standing on the other side of the main door the Sensorites talk to Susan telepathically asking her to ask the others whether they can talk about why they are here as long as the humans don't hurt them. This is agreed to. The Sensorites tell the humans that the reason why they have trapped them is that the last time that they allowed humans on to their planet the Sense Sphere was nearly ruined with prospectors mining Molybdenum and they will not allow this to happen again. They inform the travellers that they have allocated an area of the Sense Sphere where the humans can live in peace but they mustn't leave. The Doctor confronts the aliens and says that he will not be going to live on the Sense Sphere and demands the lock to his TARDIS back, The Sensorites leave to decide what to do. The Doctor notes to his companions that the Sensorites had very heavily dilated eyes in the light which measn that in semi-darkness they would be almost blind. It is then that the Sensorites contact Susan again, She appears to be agreeing to something. On being questioned to what she is agreeing to she informs the Doctor that she has agreed to go to live on the Sense Sphere with the Sensorites as they threatened to kill all of the humans otherwise. Two Sensorites take Susan away and the door to the control room closes.
