The Algebra Of Freedom, Arches, Glasgow

Two off-duty policemen mull over the dead Brazilian they shot dead on London Underground in the mistaken belief he was a terrorist. A Muslim taxi driver at the end of his tether is tempted into extreme measures. The Muslim, Parvez, and one of the policemen, Tony, are haunted by ghosts late at night as external pressures attempt to force their hands. When worlds eventually collide on a late-night cab ride, the blast looks unavoidable.
