In 1920 Ireland, the ordinary people of the land unite to form volunteer guerilla armies to face the ruthless Black and Tan squads that are being shipped from Britain to block Ireland's bid for genuine independence. As the freedom fighters' bold tactics bring the British to breaking point, a treaty is declared. But, despite the apparent victory, civil war erupts and men who have fought side by side, now find themselves pitted against one another as enemies, in disagreement about the treaty signed with Britain. Some say it's not real freedom for the Irish, while others see it as a start.
