A wealthy eccentric constructs a replica of the House of Usher on mars and populates it with robotic entities from literature. Due to a strict, "no imagination law," he is visited by a government official who he has killed. He invites high ranking officials to a costume party in the house, and systematically kills them off based on deaths from literature, mainly Poe's work. He replaces the officials with robots at the party and then seals the last guest inside a wall. Then the house falls apart.
