Christopher Walken stars as a scientist out to protect his project, one that involves being able to experience the senses and emotions of another person, from getting into the wrong hands.  Natalie Wood, in her final film role, co-stars as the wife he is about to lose, if only they could remember the love they once had.  Special effects wizard Douglas Trumbull directs this troubled but still intriguing science fiction exploration that was, perhaps, too ahead of its time to transplant what he envisioned into our own minds.
