A battered bus gives context to graphic scenes of refugees in persecuted flight. Harried and humiliated by sneering men in uniform, the migrants still try to set up little homes, retain a sense of identity, often through music - and, above all, protect their children. The adult performers constantly watch over life-sized models of (unnervingly realistic) youngsters. When the group is repeatedly forced to scramble for safety - inside or on top of the bus - the children are swiftly passed from hand to hand, like precious parcels of hope for a better future. Callous violence, valiant beauty and plaintive humanity over-lap and collide as history repeats in a fiercely physical Silence that asks troubling questions. A viscerally memorable experience for those who stand and watch.
