In England, the times are a-changing: it's mods and rockers. On the day Nancy arrives in London, suitcases in hand, looking for the YWCA, Colin has had enough of missing out on the sexual revolution. He begs his smooth (and misogynistic) pal Tolen to teach him 'the knack' - how to score with women. Serendipitously, Colin and his new lodger Tom meet up with Nancy while Colin's buying a bed larger than Tolen's. The three hit it off, but their simple fun ends when Tolen meets Nancy. Colin is jealous but impotent, and Tolen both attracts and repels her. She swoons, wonders what happened, and cries 'rape.' Impish serendipity rubs against unsettling ambiguity; Tolen bolts.
