Police detective John Calvino is visiting the confines of a state hospital to interrogate Lucas, a mentally disturbed fourteen-year-old who´s just confessed to a horrific crime. The boy seems wiser than his years - and eerily knowledgeable about asimilar crime that occurred in John´s hometown some twenty years ago. Later that night, reunited with his family, John cannot shake the uneasy feeling that there´s an unseen presence in the house with them. As the signs of haunting begin to increase, darkness descends over the once happy family. But nothing can prepare John for the dread that will grip him thirty-three days later, when a multiple murder confirms his suspicions. Crimes from the distant past have started to repeat themselves, and, John knows, they will culminate on the night of his son´s fourteenth birthday - when a killer John thought he had long ago vanquished returns to exact his revenge at last.
