Cyprus Avenue is David Ireland's subversively funny and savage new play about one man trying to make sense of a radically changed world. Eric Miller (Stephen Rea) is a Belfast Unionist. He is exclusively and non-negotiably British. But nowadays he is worried he might be Irish. When Eric sees a likeness between his new-born granddaughter and the Irish republican leader, Gerry Adams, his sanity starts to unravel. Determined to defend his family and his heritage, Eric's lifetime of ingrained prejudice and unsettled identity push him to the edge.
