When Johnny Dixon and his friend Professor Childermass discover an old heirloom clock, the terror begins. The professor suddenly vanishes, and Johnny is left to solve the mystery--alone.

Inside the clock Johnny discovers a miniature room, a room exactly like the one in which a murder took place long ago. And from the inside the little room Johnny pockets a tiny skull with magical powers. But taking the skull is a terrible mistake--for dark demonic forces are unleashed the minute he picks it up.

Enlisting the aid of his friends Fergie and Father Higgins, Johnny embarks on a harrowing chase to a deserted island off the coast of Maine--where he must confront something more terrifying than his worst nightmares.
