Cool Hand Cooper mails himself in a crate from jail seeking the hustlers' aid. He is due for parole but fears for his life having stolen diamonds from the Mafia and asks the team to retrieve them for him. Unfortunately a police station has been built over the burial place calling for a complex plan of action,involving a traffic jam to snarl up London and to call the cops out and the supposed repair of faulty drains to justify digging. The rocks are recovered but,with the help of Albert's friend Yusef,the hustlers claim them for themselves. Albert himself sits out the operation as he meets his long lost daughter.
