Shadow of Fear was the 12th episode Produced and the 19th Broadcast episode of the series Captain Scarlet And The Mysterons.


Spectrum are trying to decieve the Mysterons and take pictures of the planet Mars. But are the Mysterons to clever for them, will they be found out and stopped.


In the Himalaya Mountains is the K14 Observatory where Dr Breck, Dr Carter and Dr Angelini who are sitting at desks carrying out an experiment. In the room with them, is Captain Scarlet and Captain Blue who are observing what is going on. The Doctors were counting down to begin the picture transmission from a satellite that is getting closer to Mars.

As the Satellite reaches Mars it explodes, but the scientists don’t know this, so they start the countdown. Everything seems to be going according to plan. They are hoping that the satellite will send them pictures of Mars. But two seconds before the first pictures are transmitted the countdown stops, telling them that the satellite has been destroyed

However, they are not disappointed, because it is all part of a plan called “Operation Sword”. They want the Mysterons to believe they have destroyed the real satellite so they can send the real one without it being detected. At the moment, the real satellite is hiding behind a large rock, which is going past Mars. Once it reaches Phoebus (one of Mars’ moons) it will land on it and begin to take pictures of Mars.

They’ll receive the first pictures at the K14 Observatory tomorrow, so they all go to bed besides Captain Scarlet who is on night watch and Dr Breck who couldn’t sleep. He is looking through a telescope watching Mars. Suddenly, Mars starts giving off huge amount of light, which effects Dr Breck, until he collapses on the floor dead. Slowly two green rings pass over him and standing besides the body is the Mysteronized Dr Breck!

Once everyone wakes up they find that Dr Breck is missing and there is only a few minutes before they begin the countdown to receive the pictures. So Captain Scarlet and Captain Blue set off to find him, while Dr Carter and Angelini begin the countdown.

While Captain Scarlet and Captain Blue search outside, Dr Breck is in the Gear Rotation Room. There he attaches a bomb to one of the gears and then heads outside. Helping Captain Scarlet and Captain Blue search is Melody Angel and Captain Grey who are inside a Spectrum Helicopter.

After a long search they find Dr Breck hiding on top of a cliff face. Once they arrive, he tells Captain Scarlet and Captain Blue about the bomb he has planted. Saying that the moment the receiver on the top of the Observatory turns, the bomb will explode. He then fires at Scarlet. In retaliation Scarlet shoots Breck killing him.

They try to rush back to the Observatory in order to warn Carter and Angelini, but they are too late, the receiver turns causing the bomb to go off destroying the Observatory and killing Carter and Angelini.

Despite the failure of not receiving the pictures, Colonel White states that Operation Sword shall continue as planned.
