Synopsis: Marcus, a wealthy widowed English author brings Elise, his beautiful young bride, to his isolated home in rural Spain. Elise's new life of comfort turns nightmarish when her 12-year-old step-son begins behaving more than a little strangely. The brilliant and lonely child is out to destroy all the love and trust between his father and step-mother with his surreptitious pranks. He revels in exploiting and feeding Elise's paranoia about him and plots to drive a wedge deeper between her and Marcus...or is the poor child simply the victim of a neurotic woman's overactive imagination?
