Relates the four sexual escapades that take place in a London apartment.

Professors Vrooshka and Crump decide to visit an archaeological site to study the artifacts there. Lo and behold, it's right next to a caravan site where all manner of people are staying. With a randy Major owning the site, a snobbish mother, and the two professors' constant innuendos, the film ends with a sinking caravan site and a striptease performance as a replacement for the cabaret night.

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.
