Illegal pornography has been flooding the streets of urban England. Local dealer Pete Hunter, whose shop is located at 313 High Street, orders some pornographic photographs from his supplier, Niko, who addresses the package to "P. Hunter" and inadvertently sends it to 131 High Street instead. At that address is a Barclays Bank branch, and upstairs is a flat belonging to the bank where bank executive David and his wife Penny, just back from their honeymoon, live; their last name is also Hunter. When the package arrives at 131, David and Penny, thinking that the P. Hunter is her, are horrified at the contents, not only because of the salacious material, but also because David's boss, Mr. Bromley, has previously fired without question others who possessed such materials. David's bank colleague, head cashier Brian Runnicles, helps them try to dispose of the photos before they're seen by Mr. Bromley, David's visiting mother Bertha, or the police. But getting rid of the evidence is more difficult than they expect and Pete Hunter just keeps ordering more porn which gets delivered to 131.
