Two Italian immigrants and acknowledged anarchists are caught amidst communist witch-hunts and judicial negligence when they are tried and executed for murder in 1920s America. Based on the true-life case, considered by some a flagrant miscarriage of justice and political martyrdom, by others, honest American judicial-system proceedings. Well-made and acted. Joan Baez sings the title song "The Ballad of Sacco and Vanzetti."
