Carl Weathers

Two former cops come out of retirement to help Shawn and Gus solve the murder of a former police chief.

After the rescue of a young girl from a sex trafficker, Benson (Mariska Hargitay) and Stone (Philip Winchester) must take drastic measures to reunite her with her mother. Meanwhile, Rollins (Kelli Giddish) decides to give her rocky relationship another chance.

After a hooded man open fires on their patrol car, Roman (Brian Geraghty) is left wounded and Burgess (Marina Squerciati) takes off after the shooter, briefly losing sight of him, and shoots when she relocates him turning in her direction with a glimmer of silver in his hand. No gun has been found at the crime scene and the shooter is identified as a 17-year-old honor student who will likely never walk again due to his injuries. Protests begin as the public views the case as another incidence of a police officer shooting an unarmed African American teenager. Assistant State Attorney Peter Stone (guest star Philip Winchester), the same man who sent Voight (Jason Beghe) to prison, has been assigned to help defend Burgess and conduct his own investigation under the supervision of State Attorney Mark Jefferies (guest star Carl Weathers). Stone and his team need to collect enough evidence to indict the teen and clear Burgess, but must tread with caution on this high profile case as tensions run high.

When Lindsay (Sophia Bush) is tipped off about a grieving father looking to avenge his daughter's death, Olinsky (Elias Koteas) goes undercover as a hitman for hire. With Gang Intelligence lacking enough evidence to arrest the original gangbanger in question, the team works to reinvestigate the case. Meanwhile, Ruzek (Patrick John Flueger) comes back after finishing his undercover assignment only to have Voight (Jason Beghe) knock him down to patrol duty.

After a female jogger is brutally murdered in the park, Rixton (guest star Nick Wechsler) and Atwater (LaRoyce Hawkins) arrive to see two suspects fleeing the scene. When the men make their way inside a church, the priest and parishioners gather outside to block law enforcement from entering. While investigating the case, Rixton gets caught in a lie with Voight (Jason Beghe).
