A group of Holocaust survivors and their families gather in Prague’s Old Town Square to recreate a photo that was taken in 1945, when the survivors had just been liberated from Nazi concentration camps. The survivors were part of a group of children flown to the UK to start new lives after World War Two. Unlike the Kindertransport - which rescued thousands of children in the early years of the war - this group had been through the concentration camps and survived against all odds. BBC reporter Hannah Gelbart, a granddaughter of one of the survivors, tells the story of the orphaned children who had everything taken from them, and re-built their lives together.
