Romulus Ledbetter (Jackson) was a talented Julliard-trained musician, but paranoia drove him away from his family and into a cave in the heart of New York City's Central Park. There, he lives in seclusion, raving about the influence of a powerbroker he believes is the center of all evil in the world. One day, the corpse of a homeless boy appears near his home. The crime leads Romulus away from his cave and out into the real world, where he eventually infiltrates high society to solve the mystery.
