Dolores Huerta wanted to be a dancer. Instead, as Angela Davis marvels in Peter Bratt’s essential historical documentary, she became “a dancer on the stage of justice.” A talented and tireless community organizer, Huerta discovered her purpose among the perennially exploited Latinas and Latinos laboring for Northern California agribusinesses. She founded the United Farm Workers with Cesar Chavez in 1962 and directed the decisive national boycott of Delano grapes that impelled the growers to sign labor contracts. Despite her remarkable record of success, however, she encountered resistance as the lone woman on the UFW board. Still, nothing could slow Huerta’s war on poverty, pesticides, injustice, and racism—until a San Francisco cop badly injured her during a Union Square protest of then Vice President George H. W. Bush in 1988. Bratt deploys remarkable and little-seen archival footage along with highly emotional interviews with many of Huerta’s eleven children. Their sacrifices, along with hers, are shown as heartbreaking but necessary elements of this major, often overlooked chapter in California history.
