Colin is a nervous schoolteacher working in London, observing rather than participating in the sexual revolution of the 1960s. He has little personal sexual experience and wishes to gain "the knack": in this case meaning a way to seduce women. He turns to a friend, a confident, womanizing drummer known only by his surname, Tolen. Tolen gives him unhelpful advice to consume more protein and use intuition, acknowledging intuition is not something that can be completely learned, and advocates the importance of domination of women. He then suggests that Colin should move into his home, where he and another friend "share" women.
