Street photographer Vivian Maier was a mystery even to those who knew her. A secretive nanny in the wealthy suburbs of Chicago, she died in 2009 and would have been forgotten. But Maloof, an amateur historian, uncovered thousands of her negatives at a storage locker auction and changed history. Now Maier is hailed alongside the likes of Diane Arbus, Robert Frank, Henri Cartier-Bresson, and Weegee as a major artist. And that is just where the story begins. Finding Vivian Maier follows the filmmakers as they unearth Vivian’s story, combing through thousands of negatives and tracking down the families she worked for and others who remember her. The story that emerges goes beyond clichés of the undiscovered artist and a strange life to ask as many questions about ourselves as it does about her.
