The farce surrounds an assistant bank manager, Peter Hunter, who lives in a flat above his bank with his new bride Frances. When Frances innocently sends a mail order off for some Scandinavian glassware, what comes back is Scandinavian pornography. The two, along with the bank's frantic chief cashier Brian Runnicles, must decide what to do with the veritable floods of pornography, photographs, books, films and eventually girls that threaten to engulf this happy couple. The matter is considerably complicated by the presence of Eleanor (Peter's mother), Mr. Bromhead (his boss), Mr. Needham (a visiting bank inspector) and Vernon Paul (a police superintendent).
