At the Barricades, a play drawn from original sources by James Clements and Sam Hood Adrian, explores the price of freedom and the complexities of political idealism. The play highlights the fight of the Abraham Lincoln Brigade, a battalion of international volunteers numbering roughly 2,800 Americans who fought on the side of the Republicans (the democratically elected government) during the Spanish Civil War (1936–39) against the Nationalists, the rising fascist dictatorship under Generalissimo Francisco Franco.
