New York City in the early 1980s is broke, crime-ridden, and covered end to end in spray paint, and this film treats that paint as the real story. Henry Chalfant, the photographer who spent years documenting subway graffiti, appears alongside teenage writers racing maintenance yards at night to hit trains before the morning wash crews, and alongside breakdancer Crazy Legs of the Rock Steady Crew, whose battles carry the same competitive charge as the tagging itself. Transit police, city officials, and art critics argue the other side, treating graffiti as vandalism and civic decline rather than art, and Mayor Koch's anti-graffiti campaign runs through the film as the establishment's answer. The writers, mostly teenagers from the Bronx and Brooklyn, talk about style, reputation, and getting their names seen citywide, oblivious to whether anyone in a gallery would call it art. Whole-car pieces painted top to bottom get buffed gray within days, and the film catches that cycle of creation and erasure as it happened, on the trains themselves rather than in reconstruction.
