Hunder is petulant, moody and prone to tantrums. He is also the bio computer that controls intergalactic travel and moves worlds. When God Arrives his mood doesn't improve, but the Supreme Deity is more interested in annihilating Hunder's mysterious communicator Ansopha, "spawn of the Devil." So the Devil enlists the help of retired photojournalist, Gladys Hodge, winter resident of Beachview in Brinton-on-Sea. The small seaside town is never quite the same again.
