Bruno is a boy who lives in Berlin with his parents and his older sister. They are a rich family because Bruno’s father is a soldier promoted to do important things for the nation. One of the conditions is that they have to move to another city, Out-with. Bruno does not like the idea because he is far from Berlin and will not be able to see his friends. The next day Bruno says goodbye to his friends sadly and they go to Out-with.

Bruno’s surprise is not the place or the house he expected, he was really close to the Out-with camp although he does not know it. Bruno did not understand anything of what was happening in that sinister place. His days were long since he was forbidden to leave the house, specifically, the back of the house. That made his desire to explore push him to run away from home and see what was in that strange place. He ran through the trees until he came to a large fence that enclosed the camp. In that instant he sees a boy sitting next to the fence. He goes to talk to him and asks him why he is there and why he is wearing blue and gray striped pajamas like all people. Bruno continues without understanding anything but they become friends with that boy named Shmuel. In all corners, hatred towards Jews is encouraged, including the teacher who educated Bruno and his sister. One day, Bruno finds Shmuel polishing glasses in a room in his house. He asks what he does there and offers him something to eat. At those moment, a soldier enters who believes that Shmuel got into the house and was stealing food. Bruno betrays Shmuel pretending he does not know him.

After a while, Bruno repents and he wants to apologize but is no longer there. For a few days Bruno goes to see Shmuel at the fence but does not appear. Bruno thinks he’s angry. At last, he met Shmuel and forgive Bruno. Bruno’s mother is not happy with the place and even less so that her children are raised in that environment. So they decide to move to a more secluded place. Just the day they leave, Bruno decides to go to the other side of the fence by making a tunnel and camouflaging himself with a pajamas that Shmuel gave him. Bruno felt indebted to Shmuel, so he helped him search his father who was missing. He marched cause they were being pushed by the soldiers. They were in a long room that was surprisingly warm…

After a long time, the soldiers had searched every part of the house, they discovered the clothes that bruno had left near the fence.The father formed a theory about what might have occurred…
