Things are never the same after Caroline finds some letters belonging to their mysterious new neighbor, Frederick Fiske. When Caroline reads about "poison" and "getting rid of the kids," she's sure Frederick is out to murder them so he can marry their mother.

Joining forces with their friend Stacy, a future news reporter, the team begins gathering evidence to expose Frederick. Thanks to J.P's electronic know-how, Frederick will be in for a shocking surprise.

The trap is set. Nothing can go wrong -- until the lights go out!
