Eddie Huntly, an east coast radio personality, moves to San Francisco to marry Thea, the sister of his best friend Neil, a successful entrepreneur. Shortly before Eddie's arrival, Neil is found murdered in what the police surmise was a simple mugging gone awry. As the sullen Eddie steps in as interim host of his old friend Dean's late-night talk-radio show, he obsessively makes regular visits to the forested spot where Neil's corpse was found. One such visit unleashes a chain of unpredictable events that sends Eddie snooping into the life of a sleepwalking drifter with a mysterious past.

As fiery instinct clashes with calm reason, their unlikely but powerful partnership is the only thing capable of leading their crew through unimaginable danger, boldly going where no one has gone before. The human adventure has begun again.
