A century after the formation of the first Northern Irish women's football team, 'Derry Girls' Tara Lynne O'Neill's debut play, enacted by an all-female cast, chronicles the courage and determination of the women who became known as the suffragettes of soccer. In Belfast in September 1917, in the midst of World War I and one year after the Easter Rising, a group of women representing the teams Celtic and Distillery got together to play football in front of 16,000 fans at Grosvenor Park.
