Alive again is about an average teenage girl named Faith Joy who had a terrible accident while driving to school. She was hit by a drunk driver and now is in a hospital trying to fight for her life in a coma. She gets stuck in a bed knowing that there is a person stalking her but can't do anything because she can't wait up. Little did she know it was a boy around her age who was living for more then a hundred years that is going to be either her saviour or.... Her murderer.
