The boy in the striped pyjamas

The Boy in the Striped Pyjamas is a 2008 historical drama film written and directed by Mark Herman. It is based on the 2006 novel of the same name by John Boyne. Set in World War II, the Holocaust drama relates the horror of a Nazi extermination camp through the eyes of two eight-year-old boys. Bruno, an eight-year old German living in Berlin, is uprooted to rural occupied Poland with his family after his father Ralf, an SS officer, gets promoted. Bruno notices a concentration camp near his back garden from his bedroom window but mistakes it for a farm; his mother Elsa forbids him from going in the back garden.
Removed from school, Ralf organises Herr Liszt, a private tutor, to teach Nazi propaganda and antisemitism to indoctrinate Bruno and his sister, Gretel. Combined with her crush on Lieutenant Kurt Kotler, a young colleague of her father's, Gretel makes her fanatical in her support for the Nazi agenda. Bruno struggles to adjust to the rhetoric in the teaching after Pavel, a doctor-turned-family slave, comes to Bruno's aid after he sustains a minor injury.
Bruno sneaks into the woods, arriving at a barbed wire fence surrounding the camp. He befriends Shmuel, another eight-year old boy. Both boys are made completely unaware to the true insidiously horrific nature of the camp: Bruno believes the striped uniforms that Shmuel, Pavel, and the other prisoners wear are pyjamas, while Shmuel believes he is only there temporarily and that his grandparents died from an illness on the journey to the camp. Bruno meets Shmuel regularly, sneaking him food, and learns Shmuel is a Jew, brought to the camp with his parents.
Elsa inadvertently discovers from Kurt that Ralf's promotion consists of overseeing the camp and angrily confronts her husband. Later that night, Kurt reveals his father left Germany for Switzerland to avoid national service and is berated by Ralf; embarrassed, Kurt viciously beats Pavel for spilling a glass of wine. Bruno sees Shmuel working in his home, and offers him cake. Kurt finds Bruno and Shmuel socialising and berates Shmuel. After seeing him eating, Shmuel informs Kurt that Bruno offered the cake, which Bruno fearfully denies. Bruno tries to apologise to Shmuel later, but he doesn't reappear at the fence for several days. Bruno clandestinely sees his father and other soldiers reviewing a propaganda film about the camp's conditions as positive. Bruno then hugs his father. Ralf informs his family that Kurt was transferred to the Eastern Front; angered, Elsa reveals the reason for his transfer was because Kurt did not initially alert the authorities about his father. Bruno continues returning to the fence and eventually, Shmuel reappears, but with visible injuries. Bruno apologises and Shmuel forgives him.
