Late one restless night while out for a walk, Christopher James Saunders is struck and killed by a drunk driver. His consciousness survives, however, and wanders through his hometown, trying to make sense of his new existence. He has little success until he meets an unusual woman, Samantha Lilly. Samantha has explored the spiritual realm and promises to help Chris "cross over" to where he's supposed to be. Then a fluke occurrence during the crossover gives Chris the chance to return, now able to speak directly to people's souls. It's a gift he uses to help them with their fears and torments. But Chris is also tormented. He is being terrorized by a dark entity he calls the shadow man. Who is the shadow man, and what does he want with Chris? As Chris and Samantha work together to help others and to try to solve this mystery, they fall in love. But Samantha has a vulnerability of her own, which places them both in danger during their final showdown with the shadow man.
