The District S04E01 - Jack's Back

Mannion returns to Washington, D.C., from his Arizona vacation and is determined to get his job back. He starts campaigning for being Chief of Police, even though it's not an elected position. While it might get his job back quicker, Mannion chooses to save the illegal wiretapping for future use. He moves into a building slated for demolition in a poor neighborhood. Meanwhile, Brander decides to go back to the force and teams up with Nancy to investigate Lester Richard's death, for which Temple got arrested. They discover that Maria "Cashmere Brown" Rodriguez was lying, which frees Temple but doesn't exactly prove he didn't kill Lester vindictively. Also, Mannion works outside the system to clear Temple.
