History is made one step at a time. The film follows legendary organizer César Chávez’s efforts to organize 50,000 farm workers in California, some of whom were braceros — temporary workers from Mexico permitted to live and work in the United States in agriculture, and required to return to Mexico if they stop working. Working conditions are very poor for the braceros, who also suffer from racism and brutality at the hands of the employers and local Californians. To help the workers, César Chávez (Michael Peña) forms a labor union known as the United Farm Workers (UFW). Chávez’s efforts are opposed, sometimes violently, by the owners of the large industrial farms where the braceros work. The film touches on several major nonviolent campaigns by the UFW: the Delano grape strike, the Salad Bowl strike and the 1975 Modesto march.
