Bruno was very upset to find Maria, their maid, in his room packing his things. He did not want to move from his home in Berlin!
Bruno's mother explains to him that they are moving because of his father's job. This makes Bruno very upset!
After arriving at his new home, Bruno decides to explore "Out-With". He takes a walk through the woods until he comes to the camp.
Bruno discovers Shmuel, the boy in the striped pajamas, on the other side of the fence.
Bruno doesn't understand why he is on the other side of the fence. Shmuel is sad and appears lonely. Bruno is lonely, too. He finally feels like he has found a friend at "Out-With". Bruno joins him on the other side of the fence to try to help find Shmuel's father. Shmuel gives him a pair of striped pajamas to put on.
While looking for Shmuel's father, Bruno and Shmuel find themselves, along with others, ushered into an airtight room. Bruno had no idea what was going on, but both were led into a gas chamber and ultimately, their death.
