Growing up in the privileged confines of Dublin's leafy Rathmines, the bright, beautiful Gifford sisters Grace, Muriel and Nellie kick against the conventions of their wealthy Anglo-Irish background and their mother Isabella's expectations. Soon, as war erupts across Europe, the spirited sisters find themselves caught up in their country's struggle for freedom. Muriel falls deeply in love with writer Thomas MacDonagh, artist Grace meets the enigmatic Joe Plunkett, both leaders of 'The Rising,' while Nellie joins the Citizen Army and bravely takes up arms, fighting alongside Countess Constance Markievicz in the rebellion. On Easter Monday, 1916, the biggest uprising in Ireland for two centuries begins. The world of the Gifford sisters and everyone they hold dear will be torn apart in a fight that is destined for tragedy.
