Ian has been going to Key West every summer for years helping his Uncle Gord at his dive shop and spending as much time as he can underwater. When he's not diving he's admiring Sherri the girl who works at the dive shop and wondering how she would feel if he told her that he tastes blackberries whenever he sees her. A series of accidents leads Ian to believe that his uncle is in grave danger but the truth is more complicated and terrifying than he could ever have imagined.
