A son returns home to find the landscape of Belfast transformed. A woman talks to her son’s ghost. A man finds love unexpectedly. Ten lives act as tributaries feeding into a single river -- the Lagan, which flows through Northern Ireland. Here, specters abound, and each soul bears the weight of their nation’s violent past, producing a vivid, touching mosaic of humanity. Written by Stacey Gregg, one of Ireland’s most exciting young writers, Lagan is an intimate, engrossing portrait of people who have witnessed the tumult of war and the sudden calm of peace. But can a country, or city, ever really escape its past? This American premiere, directed by Kathryn MacMillan, runs Tuesday-Saturdays at 8pm and Sunday at 2pm.
