The plane crashed so they can arrest the pilot too. The smugglers and the pilot go with the other men and the boys and Elsa stay with the warden. That was the adventure of Hans, Karl, Otto and Elsa.
In my opinion it was a very nice and exciting because you don’t know if they go get it. And it is nice because it’s a realistic story and it’s pretty good.
