The television series was based on a play by Danish author Bjarne Reuter. In 1984 Reuter published his collection Tre skuespil ("Three Plays"); a collection containing also En dag i Hector Hansens liv ("A Day in the Life of Hector Hansen") and Kom der lys i neonrøret, gutter? ("Was There Light in the Neon Tube, Boys?") – in addition to Busters Verden.

Danish teens come of age in 1963. Bjorn and Erik are close friends. Bjorn is pursued by Kirsten, a future Stepford wife, but he falls for Anna, who initiates him into love and sex. Erik is somber, caring for his home-bound mentally-ill mother while his strict father rules his life. He desires Kirsten, but she's unattainable. Pregnancy, a horrific abortion, an engagement party, and a revelation about the rectitude of Erik's father lead to a climax: Bjorn and Erik must stand up to controlling adults.

Denmark, 1961. Bjørn, a middle-class boy in his early teens, wants to be accepted by Steen, a bullying peer of his with wealthy but freezingly cold parents. Bjørn's other good friend is Mulle, a cheerful and more childish working-class boy. All three seem friends at first, but gradually Steen starts pushing Mulle away while pulling the impressionable Bjørn with him towards more and more violence.
