All Souls is an American television series broadcast on UPN, first aired in 2001. It was a horror-drama series about a haunted Boston hospital called All Souls Hospital, and it followed Dr. Mitchell Grace's quest to find out the truth about the hauntings that dated as far back as the civil war. The program was cancelled in late August 2001 due to low ratings.
All Souls Hospital's lower levels used to be a mental asylum, and are haunted by ghosts of dead patients. The ghosts notably include Lazarus, an orderly who has been benevolently haunting the hospital since his days working with Dr. Ambrosius after the Civil War.
