When Detective Inspector Terri Marston takes on the case to prove the innocence of suspected murderer, Leonard Fallon, a number of strange events begin to occur during the investigation. At first she believes them to be purely circumstantial, until she witnesses a man being thrown from a roof by an unexplainable invisible force. It is after this that Terri comes to discover that an incorporeal being may be aiding her in her investigation; for what reason she does not know, but she suspects that someone close to her may have the answer.
