Grimley Colliery Band is a bastion of the local community and one that its leader cares passionately about. For Danny (PETE POSTLETHWAITE) it is the music that embodies the spirit of that community, representing the very lifeblood of its people. However, as the spectre of unemployment looms large on the horizon, not all the band members can share his passion. Attitudes soon change with the entrance of Gloria (TARA FITZGERALD).

Granddaughter of a former band leader and childhood sweetheart of band member Andy (EWAN McGREGOR), she has returned to her hometown. Impressed by her talent and overwhelmed by her beauty, a new wave of enthusiasm sweeps through the band as they embark on the competition circuit. However, admiration is soon dulled and her relationship with Andy threatened, by the stunning revelation that she is an employee of the British Coal Board.

Despite the surfacing conflicts, the Grimley Brass Band return triumphant from the National Semi-Finals. Their euphoria is short-lived, however, as they return to find their worst fears realized. The pit has been closed and the defeated community recoils in shock. Phil (STEPHEN TOMPKINSON), Danny’s son has now lost everything – his family, his home, his job and almost the will to live.

For Danny there is also a grave price to pay for a life’s service to the mines. As the band witness his dramatic collapse from pneumoconiosis, a defiant fighting spirit is reawaken. Aided by an unexpected benefactor, the miners unite to realize Danny’s dream and take their rightful place at the National Championships in London. As ambassadors for their community, they take a triumphant journey that will tell their story to the nation.
