When a young mass shooting survivor radicalizes into becoming an anti-government terrorist, the team must track him down before he can exact revenge on those he believes failed him.
The murder of an off-duty NYPD detective threatens to tear the city apart; Cosgrove mourns the loss of a friend and asks Capt. Benson for help solving the case; McCoy and Price disagree on how to prosecute the culprit.
Just as McCall considers quitting, she's pulled back in when she takes on Detective Marcus Dante as a new client who needs her help to find an untraceable group of bank robbers.
