The book details how African American, American Indian, and Hispanic inmates receive harsher punishments, including solitary confinement, and fewer rehabilitative programs, such as substance abuse treatment and mental health counseling. It also examines other injustices, including how female inmates suffer from a lack of rehabilitative services, Muslim inmates are placed in solitary confinement for practicing their religious beliefs, American Indians are disproportionately punished, and undocumented immigrants are forced from prison to prison in the middle of the night.
