Bruno is an eight-year-old German boy who leads a very comfortable life in Berlin during the Second World War. His father is a high ranking Nazi officer, but things change when the family has to move due to his father’s new post. In his innocence, Bruno sees the nearby concentration camp as a "farm" and wonders why its inhabitants are always wearing striped pyjamas. Eventually Bruno becomes friends with a Jewish boy his own age who lives on the other side of the fence.

. . . Elsa decides to move away with the children;
Ralf agrees, and tells Bruno that Elsa does not feel that the area is a good place for children to grow up. Bruno does not want to leave anymore, because of his friend Shmuel.

Shmuel tells Bruno that his father is missing. Bruno gives him the bad news that he will be moving away for good the next day after lunch. Wanting to make up for letting Shmuel down and unaware that his father has likely been murdered, Bruno agrees to help Shmuel to find his father, and returns the next day with a shovel to dig a hole under the fence to get into the camp, while Shmuel will bring an extra set of camp clothing; Shmuel's suggestion that he could leave the camp through the hole is rejected by Bruno, who focuses on the target of finding the father.

Bruno changes his clothes and wiggles under the fence, and is now in the camp with Shmuel. Bruno comes to realize that the camp is completely the opposite of what he saw in the propaganda film and wants to return, but Shmuel encourages him to continue helping to find his father. While they look in Shmuel's hut a group of guards and Kapos arrive and march all those inside (including Bruno and Shmuel) to a low concrete building. The men and boys are made to undress, supposedly for a shower, packed together into a gas chamber, and killed.

In the meantime, Elsa informs Ralf (who is, in a twist of irony, in a meeting about increasing the capacity of the crematorium) that Bruno is missing. With Gretel, they run to the camp and try to find him. They find Bruno's clothes next to the hole under the fence. Ralf runs throughout the camp and discovers an empty hut, and, reaching the gas chamber, concludes that Bruno has been brought to the gas chamber with a group of Jews. Pavel is also seen undressing near the boys and he looks at them and then turns away. When Ralf arrives, the boys are already dead and he is devastated. Upon hearing Ralf's cry of "Bruno!" Elsa and Gretel realise what has happened and fall to their knees in tears. A last shot showing the undressing room with many camp uniforms reminds the viewer that the tragedy is not just Bruno, Shmuel and Pavel's deaths, but that of many other Jewish people during the holocaust of World War II.
