Retired police detective Bill Hodges now runs an investigation agency with his partner, Holly Gibney --- the woman who delivered the blow to the head of Brady Hartsfield, perpetrator of the Mercedes Massacre, that put him on the brain injury ward. When Bill and Holly are called to a suicide scene with ties to the massacre, they find themselves pulled into their most dangerous case yet, one that will put their lives at risk, as well as those of Bill’s heroic young friend Jerome Robinson and his teenage sister, Barbara. Brady Hartsfield is back, and planning revenge not just on Hodges and his friends, but on an entire city.
