Clinical psychiatrist, Matt Dawson, is returning home to the seaside town of Saint Andrews after the sudden passing of his father, Stanley. Matt must put his own career on hold while he oversees Stanley"s practice. Among the patients thrust into his care is the withdrawn Morris Dykeman--a man accused of a brutal murder several years ago. As he strives to uncover his patient"s past, Matt learns of Stanley"s interest in the occult and rumors persist that he was involved in a bloody night in 1952 that changed the town forever. Now Matt searches for a rare book that can unlock the truth behind the events of that night and the killing spree that followed. But, a group of influential townspeople stands in the way and will stop at nothing to prevent Matt from learning the secrets of the Sacra Obscurum.
