Adolescent Stephen Jameson doesn't know it but he's about to break out, and several other special teenagers, as well as two thugs, hope to find him when or before he does.

Stephen has been abducted from the hospital by Ginge and Lefty, who take him to the mysterious Jedikiah. John, Carol and Kenny attempt to locate him and get him safely back to the lab.

In the Tomorrow lab, Jedikiah lays in wait to catch Tomorrow People like flies in his web of technology.

John, Carol and Stephen recover to find Jedikiah has left, taking Kenny with him. They follow them back to the mansion in order to perform a rescue, only to discover Jedikiah has set a trap for them.

John and Stephen jaunt up to the cyclops' spaceship in an attempt to rescue Kenny, Ginge and Lefty. There they finally meet the cyclops and discover the real reason why he wants telepaths.

Jedikiah is recovered from space by Count Rabowski, who is already holding prisoner Peter, one of the Time Guardians. Jedikiah tricks Peter into transporting them to the 20th century so that he can get his revenge on the Tomorrow People.

Carol and Stephen jaunt to the Tower of London where they encounter Jedikiah, who takes Carol back to Rabowski's spaceship, hoping to use her as leverage with Peter.

Rabowski finally coerces Peter into opening another Time Arch, where Jedikiah sends Rabowski to assault the lab in a prelude to eradicate the existence of Tomorrow People for all time.

TIM jaunts John and Stephen back to the lab where Kenny attempts to revive them. Meanwhile, Jedikiah forces Peter to take them back to the 20th century one last time.

The Tomorrow People investigate a series of natural disasters which are threatening the entire planet. Meanwhile, Ginger and Lefty take a day trip to Clacton and encounter a sinister pier attraction.

Ginger is brainwashed by the mysterious Spidron, who puts him to work in his mine operation. Meanwhile, Stephen and Lefty return to the pier in search of their friend.

John and Carol return to the lab where they find Stephen has been returned safely, but no one has any memory of what has happened. Meanwhile, Steen returns to the pier to continue his investigation into Spidron.

The Tomorrow People and Steen must find a way to save the workers trapped in Spidron's collapsing mine workings. Then they must track down Spidron and Sandor and stop them escaping or the entire Earth will be destroyed.

John and Stephen find themselves with two mysteries to investigate - the possibility that Stephen's new teacher Elizabeth M'Bondo is a Tomorrow Person and some worryingly accurate paintings of alien planets.

John and Stephen follow Liz into hyperspace, where they manage to rescue her and return her to the lab. Convinced of their story, she agrees to help them investigate the paintings, which seem to induce violence in those around them.

John and Stephen rescue Liz from the youths and find out about the second painting. John buys it from a man who turns out to be Robert's grandfather and takes it back to the lab, only to find out it may be a trap.

John is being held prisoner by Robert in the cellar of the antique shop, unable to use his powers. Chris attempts to rescue him but only succeeds in getting himself in trouble with the police.

Robert explains to John that his race uses violent energy as a power source. If they stay on Earth, they will die, but the violence needed to power their departure will completely destroy Earth's civilisation.

John and Stephen both begin having dreams about Peter and realise he is asking for help, but first they must track down a Roman vase that also appears in the dream.

Stephen is transported to the Hall of the Time Guardians where he meets Zenon, Peter's grandfather. Peter has become lost in the past and his only hope of rescue lies with the Tomorrow People.

John, Liz and Chris plan an attack on the gladiator training school to try and rescue Stephen and Peter, but none of them have realised Gaius' true nature.

A new peace treaty is about to be signed but the Tomorrow People are worried about the Doomsday Men, an organisation dedicated to the perpetuation of war. Stephen is sent undercover at the same school, as the grandson of the group's leader.

Stephen earns the respect of Douglas and the others and is invited to join the Doomsday Men. Meanwhile, an accident at the Damocles space station leaves an astronaut in danger, so the Tomorrow People decide to intervene.

The Damocles is in the hands of the Doomsday Men and the Tomorrow People are powerless to act. Any attempt at intervention and McLelland will throw the dead man's switch and launch nuclear missiles towards the Earth.

Stephen and Paul suspect Laird is involved in Douglas' kidnapping and follow him, only to learn the whole incident was set up by the Doomsday Men. Stephen teleports both boys back to the lab where the Tomorrow People try to convince them to help stop McLelland.

John, Liz and Stephen sense the break out of a new Tomorrow Person, Tyso Boswell. Unknown to them, however, he has already come to the attention of Professor Cawston, who introduces him to the mysterious Colonel Masters.

Cawston agrees to help the Tomorrow People find Tyso by introducing Stephen to Masters; however, as soon as Masters takes Stephen away, John and Liz lose contact with him.

Masters is now aware of the Tomorrow People's existence and is determined to harness their powers. He tries to recruit Cawston to his cause, revealing the true fate of Stephen and Tyso.

TIM summons Chris to the lab where he is able to cure John. With the rest of their friends being held prisoner, Chris comes up with a novel way to thwart Masters' plans.

The Tomorrow People are visited by Timus, an ambassador from the Galactic Federation. He tells them of the planet Pyrie, where telepaths are oppressed by the servants of the alien Khultan, and asks them to go there to help them.

The Tomorrow People meet up with Tikno, the clone brother of Timus who is on Pyrie for the same reason as them. He takes John and Stephen to meet the local telepaths, the Vesh, to try and persuade them to join forces.

Liz, Tyso and Lenda have been captured by the Veshtakers and sentenced to burning. While Stephen and Arkron try to rescue them, John, Tikno and the Vesh infiltrate the Khultan's pyramid in an attempt to restore everyone's powers.

A group of aliens stop off on Earth for supplies, but since their only knowledge of Earth's culture comes from watching cowboy films, it is not long before their visit results in violence and the Tomorrow People become involved.

The Tomorrow People persuade the British authorities to turn Elmer over to them so they can return him to the ship, but unknown to them Emily has plans for John.

When one of his colleagues goes missing after an expedition to Egypt, Professor Cawston goes to the Tomorrow People for help. They soon realise the expedition unearthed Jedikiah, who is attempting to track them down.

Tricia takes Jedikiah to the EWE, where he kills Colonel Masters. As a result, the EWE start hunting for the Tomorrow People.

John and Liz are on life support at the EWE. Their only hope of recovery lies with Stephen and Tyso, but Cawston refuses to let the boys near them, afraid one of them might be the shape-shifting Jedikiah.

John, Liz, Stephen and Tyso return to Earth to see if any more Tomorrow People have broken out in their absence.

Liz manages to jaunt aboard the scout ship with a portable version of TIM. When the ship docks with the main vessel, the group discover that a rebellion has deposed Tirayaan.

Timus arrives at the lab and he and Tyso try to find a way to rescue the other Tomorrow People and their allies, who have been abandoned on the scout ship as it is drawn into the hole in space.

The scout ship manages to emerge from the tunnel back into normal space. Unfortunately, the ship then comes under attack from Vektaan, who is determined to destroy them.

After an attack on the lab by the SIS, Mike tries to help a girl who may become a Tomorrow Person escape from the KGB.

John, Liz and Mike try to save the Russian girl from both the British SIS and the Russian KGB, with mixed success.

After the death of Pavla, the Tomorrow People decide to go on holiday, so Timus sends them to do an archeological dig on the planet Galia. There they run across two escaped slave boys.

With Mike a slave inside the camp, the other Tomorrow People attempt to drive the alien slavers off Galia.

A stranger, Jake, offers to manage Mike's band, but when Liz learns that he is the leader of a religious group called the Hearts of Sogguth, she begins to wonder what his motives are.

Jake sends John to kill Liz, but forcing a Tomorrow Person against his nature breaks his possession. John and Liz realise that if Mike plays Sogguth's drum on live television, Sogguth will be released into the world.

During solo flights in John's glider, Mike's mind connects strongly with an emerging Tomorrow Person, a sacrificial priestess in an Asian temple.

To calm Andrew down, John must play him at his own game.

A pair of odd aliens arrive on Earth with the purpose of mining a rare mineral, which can suppress telepathic powers.

To save the Earth, the Tomorrow People must overcome two criminal aliens but without the use of their telepathic abilities.
