Based on an Edgar Allen Poe tale, THE OBLONG BOX centers on two strange siblings: Sir Edward Markham and his brother Julian. After a tribe of savages inflict terrible injuries on Sir Edward, he goes to Julian's manor to recover. Unfortunately, when he arrives, Markham is immediately chained and imprisioned. But Markham manages to escape, and he begins a killing spree against those who have done him wrong. And the list of victims may very well include his brother.
