13 yr old Johnny lives in a children's home with his friends Bentley (an Old Sheepdog) and the computer, Kovac. His father is in prison and his mother on life support in a hospital for the criminally insane.
Life changes for him when Kovac detects a signal from outer space and Johnny also discovers he has a sister, Clara. A journalist investigating his story is murdered, and Johnny runs away from the children's home to find Clara. Together, they are captured and taken off the Earth in a secret space elevator by the evil Krun, and a spectacular space adventure begins.
Johnny's resourcefulness saves them from Krun but in the attempted journey home, disaster strikes as the ship they are travelling on is flung back through time to
the age of dinosaurs and then to the era of Atlantis. Johnny must use his skills to survive, return back to earth and to discover the truth about his parents.
