Syl Mandel works for SENTINEL, a government agency that deals with people born with powers, which that all lead to become villians. It’s her job to contain them or make them work for her. Her life changed when she stumbled across an electric guitar that had a demon, Melicus, in it. After accidentally making a blood pack Melicus now serves Syl for the rest of her life. There are more objects that contain demons in them. Another foe of Syl is the Penny Lane Gang and they want their boss to have a demon as well but could never find him any.
