After picking up a beautiful young hitch-hiker, Michael Anderson finds himself living in his worst possible nightmare.

Three young scientists have been recruited by the government and have spent most of their lives living and working isolated in a Biosphere in the middle of the Arizona desert. However, they all question the reason why they cannot remember anything about their childhood. Finding more and more discrepancies in their work, they begin to suspect that there is another reason for all the scientific research which has been ordered by their superiors. As they move closer to achieving their goals of saving the Earth from destruction, they discover that everything they have been told is a lie. They are not who they think are and they are not where they think they are. The three of them set out on their own determined to find the truth, but the truth is more shocking and more horrifying than anything that they ever could have imagined.
