Dr. Lorne Thorpe, a well-known pediatrician, is on a rare outing with his daughter Shawn when she goes missing. Although Shawn eventually returns, seemingly unharmed but refusing to talk about what has happened, it seems that she is not the only child who has gone missing from their Troutstream neighbourhood. Detective Beldon has been put on the case, but Dr. Thorpe's increasingly erratic behaviour is hindering his investigation. And it's imperative to solve the mystery before more children disappear.
