Nine talented young hip hop dancers face the biggest challenge of their lives. Jukebox Juniors are a dance crew from Cardiff, aged six to twelve. The crew make a last-minute bid to win the UK hip hop dance championships in London. They only have two weeks to prepare, and under the guidance of their strict dance tutor Liara, they go into rehearsal overdrive. The programme follows them through the highs and lows of the build-up to the London dance-off, and travels with them to the big event. The stakes are high: if they win the UK championships, they could get the chance to dance in the Las Vegas final and to take on the world.
