A former quiet astrologer from East Acton, Martin Trueman suddenly becomes a sensation with his stage show where he was able to demonstrate what seemed to be very powerful forms of suggestion and extremely accurate forecasts over people in the audience, including things about Sarah and her friends that he should not know.
However, his abilities have come to him through contact with the Ancient Lights, who seek to use him to enable their coming to Earth. His aim is to take over everybody on the planet, and the key to do so is given to him through a live television broadcast of his show courtesy of the Paranormal Channel. Ultimately he is only beaten by Luke, who does not have a star sign, and is dispersed along with the Ancient Lights.
