Satan wanted Nathan Berry's soul and sent two of the most evil demons he could find after them. Trouble starts when the Masters family (possessed by demons) move in next door. The Penny Masters demon immediately begins fostering resentment between Nathan and Eunice Berry. The pressure of her devilish influence is so intense that even Sarah Sarah, Nathan's pet cat, and Baroness his dog, are caught up in it. Meanwhile, almost every demon in Hell is searching for a fabulous treasure belonging to Hillbelly Clanton, she of the straggly hair, and Calamity Clanton, he of the rickety lectern. The Angels rally round, but fail to stop the demons from locating the treasure. The universe is caught up in a conflict of cataclysmic proportions.
