Stephen Jameson is a kid trying to live a normal life. This isn't easy as he hears voices and often wakes up in places and can't remember how he got there. He's been seen by doctors and given lots of drugs, but nothing helps. Then he meets a group of people living in a subway tunnel and discovers that those things he thought made him crazy actually make him a new species of human. His new friends call themselves the Tomorrow People and they are on the run from a group called the Ultra, who want to capture and control them. Leading the Ultra is a regular human man who happens to be Stephen's uncle and it turns out that Stephen's dad was once the leader of the Tomorrow People. Stephen has evolved beyond his friends, but ultimately decides to take those skills and work with the Ultra so he can find his father.
