The book is a gripping account of the Groveland Boys, four African American men falsely accused of raping a white woman in Florida in 1949, and the efforts of Thurgood Marshall, a future Supreme Court justice, to defend them. The narrative delves into the depths of racial injustice and violence in the Jim Crow South, and shows how Marshall's fight for the Groveland Boys helped to lay the groundwork for the Civil Rights Movement and the desegregation of America.
