When police officer Robert Turner woke up one Thursday morning, he thought it would be just a normal day on the force. However, when a car plunged off a bridge into a river, Turner lost his life rescuing the family inside. Now, Mannion and his team reflect on the life and death of one of their own.

After the vandalization of a mosque, Mannion questions the mosque president, who reveals that the mosque has been receiving threats. Meanwhile, Temple and Debreno investigate two other hate crimes - both with similar scenarios - involving a rabbi and an African-American, respectively. Now, before racial and ethnic tensions escalate, Mannion and his team must get to the bottom of these crimes - unaware that the perpetrator is the last person they would suspect.
