Despite leading Dinnington Colliery Band to competition success, Sue Perkins returns to South Yorkshire to find herself at the centre of a family rift that threatens to tear the band apart.
In the final programme of the series, Sue faces her toughest challenge yet: to reconcile sisters Sally and Joanne's conflicting ambitions; restore morale; and leave Dinnington with genuine hope for a long-term future.
It's a dramatic finale as the band undertake their first appearance on live television, march on Westminster, and push their self-belief to the limit as they go head-to-head with Grimethorpe - one of the best brass bands in the world. At stake is not just the survival of Dinnington, but the future of brass bands all over the land.
