To Dr. Mike Ballantine, truth can only be found in science and in concrete research. But when his best friend is killed in what looks like an assassination, Ballantine begins to question his beliefs, his knowledge, and even his sanity. Things soon turn nightmarish as Ballantine begins to have strange hallucinations that seem to be fragments of his friend's life. Then the research in his lab uncovers a shocking but undeniable truth: ghosts can, and do, exist. With the help of a brilliant CIA agent, Amber Chen, Ballantine's quest to stop his friend's murderers from obtaining the critical elements of his research pits him against a ruthless genius in a race against time.
