Demonstrating the power of the car, with its cop tires, cop suspension, and 440 cubic-inch power plant, Elwood convinces Jake that this is the new Bluesmobile. Elwood has shown up in a used Plymouth police car after having traded in their old Cadillac for a microphone.
He meets his brother Elwood (Dan Akroyd) outside the prison gate. The prisoner is released - it is Jake (John Belushi).
His personal items are returned to him, including a broken watch and prophylactics. Is he on his way to the gallows? No, he's up for 'standard parole'. We next see a prisoner being roused and escorted by two guards through Joliet Prison in Illinois. The film opens with several aerial shots of the factories and oil refineries around Chicago at night as the images pan overhead to a prison.
