Scout Finch, 6, and her older brother Jem live in sleepy Maycomb, Alabama, spending much of their time with their friend Dill and spying on their reclusive and mysterious neighbor, Boo Radley. When Atticus, their widowed father and a respected lawyer, defends a black man named Tom Robinson against fabricated rape charges, the trial and tangent events expose the children to evils of racism and stereotyping.

One evening, Hammer gives a ride to Christina, an attractive hitchhiker on a lonely country road, who has escaped from the nearby lunatic asylum. Thugs waylay them and force his car to crash. When Hammer returns to semi-consciousness, he hears Christina being tortured until she dies. Hammer, both for vengeance and in hopes that "something big" is behind it all, decides to pursue the case.
