Being a psychic sexual investigator can certainly be a stimulating way of earning a living. Terri Bizarre only has to look out of the window of her office and probe the minds of passers-by to experience their most secret sexual fantasies. But when a fresh-faced young woman called Fiona Courtley walks into her office and asks for her help, Terri knows instinctively that she is about to enter a world of desire beyond anything she has ever experienced. Fiona is concerned that her previously virginal flatmate, Rachel, has become dangerously addicted to a TV show called Imagine This in which viewers' most lustful fantasies are portrayed on-screen. Not only does Rachel spend her time pleasuring herself in front of the television in full view of Fiona, but Fiona is worried that she is beginning to find the sight of her lust-crazed flatmate strangely exciting... Will Terri manage to cool their passions, or will her insights into Rachel and Fiona's depraved desires just make things worse?
