A criminal 'friend' has the key to Miami's safe and he wants it back. This is hampered by the fact that said criminal has been caught by the police and is now in jail. Miami arranges it so that Lee, Bacon and Jamie end up in the same prison and tells them that unless they get the key for him he will make sure that the trumped up charges he arranged for Barbie to file that put them there, will be made to stick. If they can get the key then Barbie will drop all the charges and they will go free.
