It's 1968, and director William Greaves begins filming a movie scene in Central Park: an argument between a couple. At the same time, a documentary crew films the crew filming the movie. Meanwhile, a third crew films the filming of the two films. As Greaves plays the role of clueless artist, and on-set conditions deteriorate, his collaborators mutiny. The result is a head-spinning landmark of experimental film that playfully smears the line between fiction and reality, art and artifice.
