The documentary examines how 1990s streetball and the And1 Mixtape transformed basketball culture at large. In the late 1990s, a burgeoning young New York City DJ, Set Free, had the idea to set some grainy streetball highlights to a soundtrack of emerging rap music. The results culminated in what came to be known as the And1 Mixtape, a series of VHS tapes that forever transformed the game of basketball.
