Cletus is a simple but good boy, employed to look after the animals’ cages. He was born with a sort of tumor that takes the form of a sleeping parasitic twin embedded in his torso. The circus’ annual medical visits have served to keep a check on the twin’s development, but just recently Cletus has not been at all himself. He has periods of memory loss and atrocities have been committed in the surrounding areas. The question is just who is in control of Cletus’s body and what are its aims?
