Nathan's father has just been diagnosed with cancer, and the only place Nathan can go to escape the stress at home is into a fantasy world that he accesses through his dreams.
But, even there, trouble is brewing as a growing breed of 'Reactors' attempt to control people's minds.
Nathan joins a band of rebels led by a carefree woman called Rada, and as he struggles to understand her cryptic leadership style, he begins to realise that the messages he is hearing could help his father.
