Pincey and Billy become pest control experts, and take the work of another rat-catcher who does his best to get his own back.At first things go really well, but then the binmen accidently pick up their bottles of whiskey promised to a dour Scots customer, and they realise they should've set traps for the rodents, as usual things start to go pear-shaped.

Pincey and Billy decide to leave the Isle Of Dogs and rent a flat on Roman Road, Bow, East London.The landlord is a religious nut, and the other tennants are a 'palmist' and a Jewish business man who is convinced the inland revenue are after him. Pincey and Billy soon come face to face with the local fascists, and after having their van wheels pinched by them, play a game of cat and mouse.

Pincey gets a job as a car park attendant, and discovers an underground tunnel that leads to what he thinks is the door to a high street bank. He tells Billy who warns him to steer clear, but the thought of getting rich quick gets the better of Pincey and he offers the job to local gangster, Stretch, who agrees to 'blow open' the bank door and let Pincey have 10%.Not surprisingly things don't go as planned.
