Atticus Finch and his two children live in Maycomb, Alabama in the 1930s, a time of racism and prejudice. The children, Scout and Jem, are best friends with Dill who comes to visit every summer.
When they're not playing games outside, Scout, Jem, and Dill spy on their mysterious neighbor, Boo Radley, who they think was abused by his father and locked in his house, coming out at night to stalk people.
Tom is a young black man who was wrongly accused of raping a young woman. Atticus Finch, a lawyer, is asked to defend him in court.
In court, Atticus gives an incredible argument to defend Tom Robinson, presumably securing his innocence. But unfortunately, despite clearly being innocent, he is found guilty and sent to jail.
After the court hearing, Bob Ewell continues to threaten Atticus and his family, saying he'll harm and kill them. He later confronts Scout and Jem in the woods and attacks them.
He breaks Jem's arm and, before he's able to kill them, Boo Radley takes the knife from Ewell and kills him. He carries Jem home and lets Atticus take care of him.
