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. After drug addiction and homelessness sent him spinning out of the art scene for 20 years, the "Shadowman" appears to get a second chance...but will he take it?

"Shadowman" plunges the viewer into the chaotic life of a forgotten artist, from early fame as a painter and denizen of the Lower East Side, through his struggles with heroin, to his surprising comeback as street art exploded to become one of the most popular and lucrative art movements in the world. Before Banksy, there was Hambleton.
