Scout Finch (Mary Badham), 6, and her older brother, Jem (Phillip Alford), live in sleepy Maycomb, Ala., spending much of their time with their friend Dill (John Megna) and spying on their reclusive and mysterious neighbor, Boo Radley (Robert Duvall). When Atticus (Gregory Peck), their widowed father and a respected lawyer, defends a black man named Tom Robinson (Brock Peters) against fabricated rape charges, the trial and tangent events expose the children to evils of racism and stereotyping.
