Rhythm is a college student in DC who learns of Moses King, the man who started the Disciples, the largest street gang in Chicago. She reads his court case, and the inconsistencies in his trial transcripts lead her to write him, asking him if he really did kill the black Chicago congressman Perry Homes and rape his wife, Fiona.
It seems unlikely; Moses started the Disciples to make a positive impact on the black community. The Disciples head up book drives, they feed the hungry, and they start free breakfast programs with the Panthers. The letters start to flow back and forth, and Rhythm changes her major to criminal justice and becomes an attorney to fight the system that has incarcerated the man she has fallen in love with.
