Melanie arrives home from hospital after a car accident in which she was badly injured. Her plastic surgeon husband has done an amazing repair job to her facial injuries, but nobody can heal the mental anguish. Soon she begins to hear the haunting and menacing voices of two teenagers who were killed in the accident, and her marriage and job - indeed her very sanity - are threatened. Things get worse when government inspectors arrive unexpectedly at Melanie's high-tech electronics company and the board threaten to have her removed. Even her company's main rival has found out something is wrong. Her family, friends and colleagues - even those she trusts - never hear the voices, so Melanie must be going insane... or is there another explanation?
