Porn-shop owner Pete, orders some new stuff from his supplier Niko, but Niko mixes up the address with the address of the local Barclays Bank. Here, newlyweds David (the bank's assistant manager) and Penny Hunter are shocked when first photos, then films, and finally two girls are sent to them in the Bank's flat. They and their friend, head cashier Brian Runnicles (who starts to have a nervous breakdown), must deal with getting rid of the porn without letting their boss Mr. Bromley--the bank's very anti-porn manager, the local police in the form of Inspector Paul, and David's mother Bertha even suspect what is happening.—Lee Horton
