9 year old Bruno is the son of a Nazi solider. One day, he comes home, and his father takes his family and moves to a countryside. There, they live in a house called "Out-With". Bruno finds it very lonely there, until one day he sees men and boys in stripped pajamas. He is very curious about this, and goes to explore. There, he finds Shumel, a Jewish 9 year old that is in the concentration camp that Bruno's home is so close to. Though they were separated with a wired fence, they become best friends, Bruno going there everyday to talk to Shumel, and Shumel waiting for him. But then, Bruno's father says that Bruno and his sister and mother must go back to Berlin, their orginal home. Bruno isn't willing to go back because he didn't want to lose Shumel, so for the last day he was at his home, "Out-With", Bruno sneaks under to fence to see what is on the other side.
Bruno never got to see Berlin ever again.
