Ben Shadeland and Eddie Blaze are the hottest young music composers in Hollywood. Fresh off an Oscar nomination, they've just been chosen to score a big-budget horror movie by Lee Stanley, the most demanding director in film. But Ben, the creative half of the duo, hasn't written a note since his wife divorced him and got custody of their three-year-old son.

Chris Blackwood is the gambling-addicted heir to the Blackwood fortune, which includes the Sorrows, an island off the coast of northern California. The island and its castle have been uninhabited since a series of gruesome, unexplained murders in 1925, but Chris needs money, and to get it he allows Ben, Eddie, Claire Harden (an aspiring composer), and Eva Rosales (Lee Stanley's gorgeous assistant) to stay a month in Castle Blackwood.

Eddie is certain an eerie, isolated setting is just what Ben needs to find musical inspiration for a horror film. But what they find is more horrific than any movie.
