Town squares across the UK become engulfed in a sea of leg warmers and Lycra, as hopefuls turn up in their thousands for a series of open-air auditions. As Arlene and Bruno battle the elements and scour the country for the nation’s hottest talent, dancers and singers compete for the chance to perform in front of the renowned judges.

From break dancing pensioners to nimble-limbed teens, auditionees freestyle their way into the judges’ hearts with styles ranging from bangra to ballet. Arlene and Bruno are forced to make some tough decisions as they whittle the dancers and singers down in a series of gruelling call backs.

Every day the remaining contestants are faced with a new challenge, and the pressure mounts as they get increasingly close to the once-in-a-lifetime opportunity. As the decisions get tougher, Arlene and Bruno enlist some additional help and hold the curtain at a leading West End theatre. The final 20 hopefuls must up their game and win over the 2,000-strong audience with a live performance.

The journey proves emotional for both contestants and judges alike as the finalists are chosen. Thousands audition, but only 16 can go through to appear on the live TV shows.
