Mirage

When police question John Berger about the explosion that destroyed his office building, he recounts a vivid memory of playing in a chess tournament out of town.

However, there is no record of any such tournament, and John quickly becomes a suspect - and begins to realise that his grasp on reality is nothing more than an illusion.

He confides in the FBI agent assigned to investigate the explosion, and together, they uncover a terrorist operation involving brain washing - an operation in which Berger was a guinea pig.

Now, the two must work against Berger's growing insanity to stop the devastating plan that threatens the nation.
