'Operation Greylord' examines Chicago's biggest corruption trial

If you're a fan of true crime narratives, you'll have a field day with "Operation Greylord," a new documentary focusing on the uncovering of massive corruption within the Cook County Circuit Court system in the 1980s.

The documentary debuts Friday, featuring interviews with Terry Hake, the assistant state's attorney who posed undercover as a corrupt prosecutor to indict 92 members of Cook County law enforcement.

Hake and Billy Miossi join Good Day Chicago to talk about the documentary and a stirring era of Cook County corruption.
