Finch is an attorney in Meigang City, a small town in the South of the United States. After his wife died, he took care of his daughter and son alone. When talking about bird shooting, he repeatedly told his children not to harm the robins, because they only sang for humans and never did anything harmful to humans.
One day, there was a rape case in the small town. Fincher was commissioned by the district court to defend the black Robinson accused of raping a white woman. In the local area, discrimination against black people is very serious. Finch's behavior naturally aroused the dissatisfaction of many people with racial discrimination in the small town, and they tried their best to obstruct Finch's work. But Vinci didn't care about people's protests, and continued to carefully investigate the case in depth. In order to keep Robinson away from unnecessary harm, he and his daughter stayed in the detention center all night to protect him.
In the court, Vinci proved that Robinson's left hand was disabled since he was a child, and he was completely incapable of committing violence to others. He asked the court to acquit him and called on people to respect the facts and maintain human dignity and equality. However, in the face of a series of facts, prosecutors and juries with deep racial prejudice still favor the plaintiff and insist on convicting Robinson. The matter did not end there, and some white people with racial prejudice proceeded to provoke and intimidate the Vinci family. In the face of rape, Vinci did not flinch, he was still ready to continue to appeal for Robinson.
