Picking up right after the events of the Season 3 finale, detectives Linden (played by Mireille Enos) and Holder (Joel Kinnaman) are struggling to manage the fallout from their rash actions at the end of last season when they are assigned a new case — the slaughter of a “picture perfect” family, the only survivor a son (Tyler Ross) who was shot in the head during the tragedy. Joan Allen guest-stars as the headmaster of the all-boys military academy Kyle attends.
