Most people dream, many experience deja vu; some believe in reincarnation. But what if it really was possible to relive the lives of your ancestors? American CEO, Jack Sinclair, is tormented by dreams of people he doesn't know and places he's never been, making him wonder if he is going insane. A phone call from a psychiatrist in Edinburgh wakes him out of another dream. She tells him that his estranged twin brother has committed suicide. Filled with mixed emotions, Sinclair travels to the Orkney Islands off northern Scotland to attend the funeral and soon discovers troubling circumstances surrounding his brother's death. To uncover the truth, he journeys into the shadowy world locked behind the veil of consciousness via what the psychiatrist calls genetic memory. This vast ancestral inheritance is passed down through DNA and surfaces only in dreams, deja vu, or visions of past lives. With the doctor's help, Sinclair relives dramatic events from his distant past and discovers a dark secret about his family that traces back to the hill called Calvary. Throughout, he is pursued by unknown killers, and by another force of evil from which he cannot escape: the beast of his onrushing insanity."
