Yaar was born in Israel, but grew up in Germany, far away from Judaism and the story of his grandparents. As a child, his grandmother Rina was smuggled out of the Płaszów concentration camp, along with her little brother. She never talked about what happened to her during this time. Yaar's father Ilei, who was born twenty years after the war, still suffers from the Holocaust today. Yaar accuses him of having established himself as a victim.
But one day, Yaar is attacked with a knife on the street because he is Jewish. For the first time, he himself feels like a victim. And he has an idea: With the computer game “Als Gott schlief” (“When God Was Asleep”), he wants to address the Holocaust in a way that history lessons cannot. Above all, he wants to take control of his own story. Yaar sets out to visit his grandmother in Israel. He wants to find out what happened when she and her little brother were discovered by the Gestapo. But his grandmother remains silent.
Sarah and Marcel, two friends of Yaar’s, collaborate with him on the development of his computer game. Yaar decides to model one of the game’s protagonists, a little Jewish girl, after his grandmother Rina. Together with his friends, he visits Rina’s birthplace Krakow, where he uncovers a terrible family secret.
A Game becomes serious. The three friends recognize a link of past events to themselves, as they are grandchildren of the victims and perpetrators of that time. So begins a painful confrontation with their own history, which also impacts the relationship between father and son. Yaar has to find his way between the trauma of preceding generations and his own claim to an unburdened life.
