The Macros (audio story)

 was the eighth and final story in the first series of The Lost Stories, produced by Big Finish Productions. It was adapted by Ingrid Pitt and Tony Rudlin, from their original script, and featured Colin Baker as the Sixth Doctor and Nicola Bryant as Peri Brown.

The story dealt with the Philadelphia Experiment, a historical curiosity which had earlier been explored in a different but similar fashion in the BBC Eighth Doctor Adventures novel.

Publisher's summary
The TARDIS materialises on the USS Eldridge, after the Philadelphia Experiment has gone disastrously wrong. Most of the crew are dead, the ship is disintegrating, and the Doctor soon realises that the problem comes from another dimension...

As they attempt to find a way to get the ship home, the Doctor and Peri visit the distant planet Capron and meet its tyrannical ruler Osloo. But the search for a possible solution only creates increasingly dire problems. Osloo's horizons have been widened – and space and time are hers for the taking...

Part one
Two men aboard the a ship are talking. They check the instruments and repair some damage that one attributes to moisture at sea. He says the interface was a few seconds off. They discuss the countdown on board and what will happen when it reaches zero.

The TARDIS lands and the Sixth Doctor and Peri Brown walk out. Peri notices that there is thick fog outside. Peri is trying to get back to Baltimore to contact her family. The Doctor determines that they are on a ship at sea. Peri hears two men talking, but they don't see her or acknowledge her when she tries to make contact with them. They are repeating their previous conversation. As Peri tries to get back in the TARDIS to leave, the Doctor tells her that he noticed something went wrong as they were materialising, some sort of interdimensional temporal flux that caught them between two dimensions. Peri looks and sees the same two men repeating the same conversation again. They decide to investigate. Peri calls the Doctor over to the capstan where he finds it covered in a strange, green rust. They notice that the ship is being eaten away by the rust.

Up in the wheelhouse, the Doctor and Peri find the Captain and helmsman. The Doctor tries talking to them and notice that the Captain is just like the other men they saw on the ship, he can't see or hear them. The Captain initiates a 20 second countdown. Peri tries to switch off the panel, but is unable to change anything. The Doctor determines they can't interact because all this has already happened. At zero, the men on the bridge disappear. Suddenly, the conversation begins again. A life vest on the ship reads USS Eldridge and the Doctor explains that the Eldridge was the subject of invisibility experiments in 1943. They head back to the TARDIS as the conversation on the bridge starts again.

As the Doctor explains what's happening to Peri, they don't realise they're being watched by Brian Tessler and Bosun who are unaffected by what's happening on the ship. The Doctor takes a probe out of his pocket and asks Peri to find a large patch of the green rust and put the probe into it so he can take some reading back at the TARDIS. The probe has a two way communicator so the Doctor can keep track of her. Peri walks back to the capstan and the Doctor begins his diagnosis. He determines that the rust has anti magnetic elements. The Doctor begins talking to himself trying to determine where the rust is coming from.

Peri screams as she is grabbed and gagged by Tessler. The Doctor shouts for Peri. They remove the gag and Peri explains that she and the Doctor are there to help. Peri asks why they can see her. Bosun responds that Tessler thinks it was because of where they were in the ship when the test went off, but they're really not sure. They all introduce themselves. Bosun says that Tessler has been working on their problem, but can't pinpoint a time of how long that has been. The Doctor explains that the ship is caught between two dimensions and if Tessler is able to boost the power in their generators, they should be able to pop themselves in one of the two dimensions. He says he's been trying to do that but each time they boost the generators it drains away without moving the ship. The Doctor explains there is another element at play, but Tessler may find it difficult to believe.

On the Planet Capron, Commander Bundth introduces Presidena Osloo. She explains to the court that the traitor is her step-son, Commander Ezz who has been mislead by subversive elements of society. Currently, the planet uses slave labour to extract power for the city and Ezz wishes to stop this practice saying this is destroying the world. Osloo asks the council to pass judgement on him.
