The upcoming episode of AMC and ALLBLK’s 61st Street features revelations about unethical goings-on within the Chicago police department.

The clip features Andrene Ward Hammond as Norma Johnson, who has learned some new information from Lt. Tardelli (Holt McCallany) regarding what appears to be unethical and disturbing behavior.

The series takes place within the Chicago criminal justice system with people in both the legal and policing worlds trying to eradicate a criminal element within the police department. According to the official description:

A propulsive thriller which courses through the dark heart of the infamous Chicago criminal justice system as police and prosecutors investigate a deadly drug bust that threatens to unravel the police department’s code of silence. Vance (The People v. O. J. Simpson: American Crime Story, Lovecraft Country), leads an ensemble cast that includes Emmy®-nominee Aunjanue Ellis (When They See Us, King Richard), Mark O’Brien (City on a Hill, Blue Bayou), Holt McCallany (Mindhunter, Lights Out), Tosin Cole (Doctor Who, Hollyoaks), Andrene Ward-Hammond (Your Honor, Manifest) and Bentley Green (Snowfall, Sweet Magnolias).

Courtney B. Vance told Shadow and Act in April that his character, public defender Franklin Roberts, had everything working against him as he tried to save his client, high school athlete Moses Johnson (Tosin Cole) from being prosecuted for a crime he didn’t commit. He said that the challenges Franklin faced reminded him of the human condition.

“One someone sees that you’re willing to risk it all for them, then they commit to you,” he said. “‘Cause that’s his question to me. Are you in this for the right reasons? Are we doing this together? And once he knows that I got him no matter what, then there’s nothing that can get between us. And so that’s the human situation.”

Executive produced by Michael B. Jordan, 61st Street airs Sundays at 10/9c on AMC.
