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.

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.
