In the year 3000, Alana is kidnapped by evil Silverthorn, after a time travel experiment goes wrong. He takes Alana to the year 1990. With the help of Jenny Kelly and family, Alana must find Silverthorn before the time capsule leaves.

Alana, a teenage girl from the year 3000, finds herself trapped in 1990 with a criminal from the year 2500. Alone, and confused, she befriends a spirited girl named Jenny Kelly. Together they attempt to track down the time capsule which brought her there, while evading Silverthorn, the villain into whose hands it appears to have fallen.—Anonymous

Realizing that they have polluted the time stream with their experiments, the scientists from the year 3000 resolve to return Jenny and Silverthorn to their respective times and then destroy the capsule before it can do any more harm. Troubles in the year 2500, however, lead to Alana and her guardian, Lorien, returning to a devastated future. They must return to 2500 and change whatever it was that went wrong in order to cause The Great Disaster to reach Australia.—Anonymous
