Nine-year-old Bruno has a lot of things on his mind. Who is the 'Fury'? Why did he make them leave their nice home in Berlin to go to 'Out-With' ? And who are all the sad people in striped pajamas on the other side of the fence? The grown-ups won't explain so Bruno decides there is only one thing for it - he will have to explore this place alone. What he discovers is a new friend. A boy with the very same birthday. A boy in striped pajamas. But why can't they ever play together?
