Shmuel, after many conversations with Bruno, promises Bruno that he will get him a pair of striped pajamas so that he will look like the people on Shmuel's side of the fence. Unfortunately for Bruno, the pajamas that Shmuel gives to him leads up to the death of both boys. The boys, based upon their clothing (the striped pajamas) are lead into the gas chamber and put to death.
