The film's young protagonists, Scout (Mary Badham) and her brother Jem (Phillip Alford), live in the fictional town of Maycomb, Alabama, during the 1930s. The story covers three years, during which Scout and Jem undergo changes in their lives. They begin as innocent children, who spend their days happily playing games with each other and spying on the town bogeyman, Boo Radley (Robert Duvall). Through their father's (Gregory Peck) work as a lawyer, they begin to learn of the racism and evil prevalent in their town, and mature painfully as they are exposed to it. The kids follow Atticus to watch the trial, in which Tom Robinson is found guilty. Atticus arrives home to find out that Robinson has been killed in attempt to escape. By October 31 things have settled down and Scout goes to a Halloween pageant. On their way home, Scout and Jem are attacked by Bob Ewell. During the struggle, Jem is knocked unconscious, and rescued by a mysterious man later revealed as Arthur "Boo" Radley.
