On an icy dawn morning in Paris in January 1943, a group of 230 French women resisters were rounded up from the Gestapo detention camps and sent on a train to Auschwitz - the only train, in the four years of German occupation, to take women of the resistance to a death camp. Of the group, 49 survivors would return to France.
Here is the story of these women - told for the first time. A Train in Winter is a portrait of ordinary people, of their bravery and endurance, and of the friendships that kept so many of them alive.
