Ben Kingsley narrates a two-part chronicle of nonviolent political action in the 20th century, beginning with Mohandas Gandhi's resistance to Britain's 1930 salt tax in India. Also examined: the 1960 lunch-counter sit-ins in Nashville and resistance to South African apartheid in the 1980s. Kingsley won a 1982 Oscar in the title role of Richard Attenborough's "Gandhi."
