In the 1920s, political activist Jimmy Gralton built a dance hall in rural Ireland. As the hall grew in popularity its free-spirited reputation brought it to the attention of the church and politicians who forced Jimmy to flee and the hall to close.
A decade later, at the height of the Depression, Jimmy returns from the US. The hall stands abandoned but as Jimmy sees the poverty and growing oppresion in the village, the leader and activist within him is stirred. He decides to reopen the hall, and so takes on the established authorities of the church and the government.
