The year is 1993. The UK and Ireland are swept up in electrifying boy band mania. Across Dublin’s clubs, bars and schools, a feverish hunt begins, to find the next musical sensation. In the era before tv talent shows ruled, hundreds vied for stardom, but only five working-class Dubliners would have the luck to be plucked from obscurity and be thrust into the global spotlight. It’s here, we begin our story.

When dysfunctional adult Al Clancy mistakenly agrees to mind his smart-ass 10-year-old nephew Karl for a week, his job and home are placed in jeopardy. In a bold bid to save Al’s job, they steal his mam’s camper van, become best friends, and embark on a criss cross adventure, putting up posters all over Ireland. When things go wrong and the lads get cranky, one of them realises that the other one needs to grow up.
