Biography of the life of Dorothy Day (Kelly). The title refers to the religious practice of treating all people, no matter how poor or humble, as if they were visiting angels. Day was a famous activist and philanthropist of the 20's and 30's. The film traces her growth - mostly spiritual and religious - as she left journalism to become a suffragette in Greenwich Village. Eventually, Day converted to Roman Catholicism and dedicated the rest of her life to helping the poor.
