Connor Gruff (Paul Nicholls) is the lead singer in boy band Billy Goat. Every week, Connor and his bandmates, his brother Dean (Mathew Horne) and friend Rafiq (Nick Mohammed), play to packed out audiences in clubs around their home town.

Life off-stage is just as good, Connor's happily married to his childhood sweetheart Carol (Sarah Smart) with three great kids; the womanising Dean is never short of a local groupie to sleep with and Rafiq just loves making music. But Connor dreams of more – he wants to be famous.

When Connor spots an advert wanting brother-based boy bands for a new TV show he's convinced this is Billy Goat's big chance to finally make it. But he hasn't taken into account the response of their manager, Grettongrat.

Grettongrat makes clear his thoughts on the band's limitations when he states: "You're a top local turn, but that doesn't make you the next Take That."

After years in showbiz, Grettongrat (Bernard Hill) knows his Ronan Keating from his Robbie Williams and he's not about to let his biggest earning act leave town to make money for somebody else. One by one, the three members of Billy Goat must descend to Grettongrat's office under The Bridge pub to try and break free of his contract.
