When a family of four is found murdered in their home, Detectives Lupo and Bernard discover that the deaths may be related to the deceased teenage daughter's troubled friend, Bonnie Jones (Emily Meade). As Lupo and Bernard track down Bonnie, the detectives become aware of another suspect, Justin Sachs (Michael Oberholtzer), who suffers from post-traumatic stress disorder, making the case more complicated when both suspects' mental states come into question. As the case is tried in court, EADA Mike Cutter is up against a famous defense attorney, Veronica Masters (Rebecca Creskoff), who had a history with Detective Cyrus Lupo, who reveals a secret to his partner, Bernard.
