Voight, ever the strategist, builds a volatile trust with a new undercover informant, Anna Avalos (played by Carmela Zumbado). Anna has a complex past, with family ties to the "Los Temidos" gang that she is helping the police infiltrate.
The Intelligence Unit, led by Sergeant Hank Voight (Jason Beghe), is targeting a ruthless new drug ring spreading through Chicago. The investigation is high-stakes, requiring an inside man to bring down the organization from within.
Voight faces pressure to manage Anna safely while leveraging her position to get to the kingpin. Meanwhile, the FBI investigation into the death of Roy Walton continues to haunt Voight and Detective Hailey Upton, adding a layer of paranoia to the unit.
