In the 1980s, Richard Hambleton was the Shadowman, a specter in the night who painted hundreds of startling silhouettes on the walls of lower Manhattan and, along with Keith Haring and Jean-Michel Basquiat, sparked the street art movement. Critics revered Hambleton as a definitive American Pop-Expressionist artist. But uncomfortable with his own success, he alienated those around him, from art dealers to close friends. After drug addiction and homelessness sent him spinning out of the art scene for 20 years, the Shadowman gets a second chance...but will he take it?
