This documentary traces the history of experimental cinema through its most renowned authors. Jonas Mekas, Maya Deren, Peter Kubelka, Ken Jacobs, Len Lye, Stan Brakhage or Robert Breer talk about their films and how they started filming them. But what is actually experimental cinema? Were they the first? Pip Chodorov offers an initiatory journey through the depths of this outsider cinema, also using his own work and with a question in the air: why do we call it "experimental" when we mean "cinema"?
