Tromaville’s local celebrity murderess, Dolly Deadly, is a shoo-in to win Serial Killer of the Year. Unfortunately, Slasharella has designs on the title and will stoop to the lowest of lows to take the crown. The two will drag Tromaville out and turn it upside down in their fight to the death, decimating the fictional city’s population all along the way.
