A tape implicating two senior police officers in a criminal conspiracy is mistakenly delivered to Daley Videos, and Arthur and Terry find themselves placed in contact with its owner - a local major crime boss.

Arthur panics when he learns that there has been a robbery of safety deposit boxes in the City, so places all his savings in the ancient safe at the lock-up. Unfortunately, they soon catch the eye of an old acquaintance from Marbella.

Arthur decides he wants to retire and Terry helps him get out of a deal with a dubious consortium of Masonic property developers.
