Teenage Superstars charts a generation of musicians from Glasgow and Lanarkshire from 1982. Broadly speaking, it is chronologically structured, while also tracing the geographical and social connections between some of the bands (for example, the childhood friendship of Sean Dickson, Duglas T. Stewart and Norman Blake, all from Bellshill). The film's story follows the formation of the featured bands, the friendships between them and sharing of band members, the commercial success of The Soup Dragons, Primal Scream and Teenage Fanclub, and the bond between the Scottish and US indie scenes of the early 1990s before the scene they had created gave way to Britpop.
