Le knack... et comment l'avoir

London schoolteacher Colin is self-conscious about his general inexperience with the opposite sex, unlike his roommate Tolen, who has a proverbial revolving door of beautiful young women in and out of his bedroom, and who cannot help Colin just by teaching him his approach with women. While Tolen wants to rent their third bedroom to his equally-womanizing friend Rory McBryde, the two who would be able to share their female conquests with Colin, someone unknown to them swoops in to rent the room: Tom, who seems more concerned about getting rid of its drab brownness--including Colin's furniture in the furnished room--to a more pristine white. Evolving in thought, Colin ultimately comes to the belief that his lack of success with women is due to the small size of his bed, and he wants a six-foot bed like Rory's. On their way back from the junkyard where Tom knew of such a bed with a wrought-iron frame, Colin and Tom literally pick up Nancy Jones, who has just arrived in town and was looking for the YWCA. Naive Nancy has a quick learning curve in her dealings in London with this collective: Tolen sees her as another conquest, while Colin thinks she can get him out of his rut. As this foursome wanders around London individually, in small groups, or as four, those they encounter act as a Greek chorus commenting on their goings-on.
