Teya Sepinuck's pioneering Theatre of Witness puts marginalised people at the core of a performance in which they tell their own, sometimes shocking, stories to the public. The film explores her engagement with a cast of women drawn from politically diverse backgrounds and views. It includes Kathleen whose husband was blown up by the IRA in 1990 and Anne, a former member of the IRA, whose uncle was killed by the Army on Bloody Sunday in 1972. Their process is an adventure in collaboration and creativity that surprises even the performers of this unusual form of theatre.
