Lock, Stock...

Miami Vice is having accountant problems, they keep turning up dead! Not only is someone skimming money from his operations but Moira is holding out her 10% of Lapland. The boys unwittingly get involved and end up having to pay Miami £20,000 each. Jamie needs to borrow the money from his uncle and has to 'babysit' a friend of his uncle's called 'Two Sips' who is returning to England for a few days.

Miami Vice goes into the meat business and employs the lads to pick up a consignment being delivered by three psychotic Russians. Moon's country cousins get involved with them and a fight over a prize bull. Meanwhile a drug crazed duo want their revenge on Miami and intend to get their own hands on the beef to exact it.

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.
