A prim young lady needs a favor: help her father beat a bum drug rap. But when Dad's boat detonates outside Miami Harbor, Matt discovers that young Amy isn't as innocent as she looks. Lured to the Bahamas, he will discover an unlikely pack of fanatics hatching an explosive plan, and that daddy's little girl is surprisingly deadly.
