Isabel and Marcus Raines are the perfect couple. She is a well-known novelist: he is a brilliant high-tech game inventor. They've been married for five years and still enjoy a marriage filled with romance. But one morning, Marcus disappears. Isabel dials his mobile phone for hours, but when she finally receives a call in return, it's more disturbing than she could have imagined - only the sound of a man screaming pitifully. The police are no use. It could have been a television show, they tell her. Grown men just don't disappear. And now the chase is on, because Isabel will not rest until she finds the truth.
