A political thriller aims to shine a light on journalistic truth and morality amid the Rwandan genocide.

Ken Urban's Sense of an Ending, directed by Jonathan O'Boyle, marks the 21st anniversary of the genocide and asks if forgiveness is possible in a situation where truth can be difficult to find.

Charles, a New York Times journalist, arrives in Rwanda for an exclusive interview with two nuns who were charged with war crimes during the 1994 genocide.

The nuns must convince the world of their innocence or be faced with a lifetime in prison, but when an unknown survivor contradicts their story the reporter must choose who to believe.

This is the first of Mr Urban's plays to be presented in Europe and the script won best new play at the Williamstown Theatre Festival.

Producer Jessica Campbell says: "Ken's compelling script explores so many questions: how can a journalist balance his loyalty to the people he meets and his duty to report the truth? How can a nation ever heal after such devastating loss of life? We're excited - if somewhat daunted - to be exploring these questions in this world premiere."

Mr Urban is a playwright and screenwriter based in New York whose awards include the Weissberger Playwriting Award, Huntington Playwriting Fellowship, and SPF/Donmar Warehouse Residency.
