Bruno's Family is moving from their old house to a new one in the country. This is for his dad's job as a Nazi commander. Bruno's grandmother was against this, but his grandfather was not. Bruno's mother was clueless on what her husband was doing, and so was supportive of this decison
Bruno is sad because he had to leave his friends behind at his old home. He has no one to play with, but one day he looks out his window to see a "farm" in the distance. He goes and asked his mom about it, but she acts like she doesn't know anything about it. She then goes and yells at her husband because he said that you coudn't see it from the house.
After looking out the window and seeing the farm Bruno decides that he was going to check it out. He follows a path that was behind the shed in the back yard that he was not supposed to go into. One day when his mom went to town he went out onto the path and ran down it. Later he found a fence and on the other side was a boy. They talked and then became good friends.
One day when Bruno was going to go and play with Smols, Smols said that he couldn't find his dad. Bruno said that he would help. He said that he would bring a shovel if he brought pajamas. The next day he dung under the fence and they ran around looking for Smols's dad.
The boys go into a hut that is full of diseased people. They start to walk around and yell for Smol's dad, but they got no answer. Then all of a sudden men with gas mask on start to walk in and push everyone out. They all walk to a building were they are told to take of their clothes. They thought they they were going to get a shower, but were really getting gased.
At the end of the movie Bruno parents know that he had left, so they go and try to save him. When they found this out it was to late, Bruno and everyone else had already been killed. Bruno and Smols had died, they were in the wrong place at the wrong time. The very last thing you see is the pajamas that they people had been wearing before they had been shoved in the chamber.
