In a flashback, John Garrett breaks a young Grant Ward out of a Juvenile Detention Facility. An establishing shot, created with stock footage, shows the exterior of the prison, which is the Cook County Jail, South Sacramento Avenue entrance, in Chicago, IL. The interiors of the facility were created on the Culver Studios stages.
