Ireland, June 1944. The crucial decision about the right time to start Operation Overlord on D-Day comes to depend on the readings taken by Maureen Flavin, a young girl who works at a post office, used as a weather station, in Blacksod, in County Mayo, the westernmost promontory of Europe, far from the many lands devastated by the iron storms of World War II.

The painful story of Ireland and the Irish people, who struggled for centuries to free themselves from the tyrannical clutches of the British Empire; an epic tale of poverty, hunger, despair, violence and unyielding courage.
