The summer of 1936 is beautiful, but Europe is on the verge of terrible change. Through that glorious summer, at the very edge of Europe, in Ballybeg, Donegal, the Mundy family shelter in their small home - five sisters, on brother and Michael, the love child of Christina, the youngest sister. The film is seen through the eyes of the boy as he feels the joy and security of his close-knit clan, but its secrets and sorrows begin to break through. They will tear this world apart. The arrival of Gerry, Michael's father, on his way to fight for Franco in Spain, unleashes repressed passion. The Eden of Ballybeg is changed forever. The memory of that summer haunts Michael forever, memories of love and loss, of women dancing, dancing as if their lives depended on it.
