Shelby Belgarden isn't exactly thrilled when people start thinking Greg is her boyfriend. After all, she's more interested in the athletic Nick Jarvis. But one day Greg suddenly becomes more interesting to Shelby -- though for all the wrong reasons: Shelby begins to suspect that Greg is responsible for the series of arsons that have occurred in her small New Brunswick town in recent weeks. After finding out that Greg and his father had moved to this town after their old home burnt down - with Greg's mother inside - Shelby finds Greg's gasoline-soaked mitten near the scene of the latest arson.
