When a turn of the century prison reformatory is slated for demolition, a grisly discovery is made. Hidden deep underground beneath the west cell block is a sub-basement structure that has not been entered in 100 years. Inside are the skeletal remains of several brutally slain children. As a CSI team arrives at the prison, an even more disturbing discovery is made that will eventually unveil a legion of seven demons and their even more chilling origins: each demon is responsible for one of the seven deadly sins. Seven deadly sins...Seven deadly demons...Seven more deadly ways to die...
