Britain 2099. All human diseases have been eradicated by genetic cleansing, but there are still people who are 'unclean' and locked away in institutions. Travis is one of them, until one day Dr Alexander helps him to escape to a world where nothing makes sense.

Travis has powerful seizures which take him and his new friend Demi on a quest through time to seek and destroy Chase, the man he hates. Along the way he has to deal with shocks, surprises, traumas, and death, until at last he ends up on a beach, where his fate will finally be decided.
