The NFB began as a government institution dedicated to showing Canadians to themselves, but nobody suspected such a simple idea would inspire an amazing group of filmmakers to revolutionize documentary filmmaking in Canada. Colin Low, Wolf Koenig, Bill Greaves, Roman Kroitor and Terrence Macartney-Filgate pounced on the possibilities that came with the hand-held camera--and invented a new kind of film language to tell their stories. Unit B, Part 1 documents how they broke with convention--and working as a creative team, produced undisputed classics such as Corral, Paul Tomkowitz: Street-railway Switchman and City of Gold.
