A prominent architect, Sir Bernard Storm, has accepted a lecture tour in the USA when he receives an offer, from Australia, to design a new leisure center. Unable to do the work himself he leaves it in the hands of his slacker assistant Henry, assisted by their efficient secretary Hilary. Henry, having trouble coming up with an idea for the design, in a drunken stupor hits upon the idea of modeling the building on the shape of a woman's breast. Naturally he then has to search for the perfect female breast.

Accident-prone Gil wants a steady job but is dismissed by every company that recruits him due to his unfortunate habit of ending up in sexually embarrassing situations. His girlfriend Annette says that she will marry him only if he can stay employed for at least a week. Hired by Mr Grimwood's cleaning company "Here To Service You", Gil is unwittingly drawn into a series of bawdy misadventures: sharing a bath with a married woman and getting caught by her husband; having a threesome with a hospital patient and a woman doctor, followed by a foursome with Annette, Grimwood and a woman psychologist; awkward encounters with a gay man and a lesbian; and getting caught by Annette playing strip poker with a group of women. Incredibly, Gil remains in his job and Annette marries him, but before the couple can have their wedding night Gil collapses on the bed and passes out from exhaustion.

An uproarious version of history that proves nothing is sacred – not even the Roman Empire, the French Revolution and the Spanish Inquisition.
