It is 1942 and Eva has boarded a train to Auschwitz. Exhausted from standing up for days, she can think only of her longed-for reunion with her husband Michal, who was sent there months earlier. But when Eva arrives at Auschwitz, there is no sign of Michal and the reality of the camp comes crashing down upon her. As she lies shivering on a thin mattress, her head shaved by rough hands, she hears a whisper. Her bunkmate, Sofie, is reaching out her hand... As the days pass, they learn each other's dreams - Eva's is that she will find Michal alive, and Sofie's is that she will be reunited with her son Tomas, who has been sent to an orphanage. Sofie sees the chance to engineer one last meeting between Eva and Michal and knows she must take it even if means befriending the enemy... When Eva realises she is pregnant she fears she has endangered both their lives. But the women are determined to hold on to the last flower of hope in the shadows: their precious children, who they pray will live to tell their story when they no longer can.
