A BBC radio full-cast dramatisation of Ian Serraillier's classic wartime story. When the Germans march into Poland in 1941, the Balickis' happy family life is shattered. With their parents taken away by Nazis, Ruth, Edek and Bronia are forced to fend for themselves in the dangerous, war-ravaged city of Warsaw. When Edek is captured too, the girls are desperate. Then they meet orphaned street urchin Jan, who carries with him a talisman of hope: a silver sword paperknife that they recognise as having belonged to their mother. Realising that their parents may still be alive, Ruth and Bronia set off on an epic journey to Switzerland to search for them. With Jan by their side, they are determined to reunite the family - and their first step is to find Edek. But the road ahead is full of danger and hardship, and they will face many challenges along the way... This moving story of friendship, courage and solidarity stars Sarah McDonald Hughes as Ruth, Stephen Hoyle as Edek, Hester Cox as Bronia and Aqib Khan as Jan. Duration: 1 hour 30 mins approx.
