<P> After the funeral of his mother, who was killed in Berlin by an enemy bombing, Ralf tells Bruno and Gretel that their mother suggests that they go to live with a relative because it isn't safe there . Their mother suggests this because she doesn't want her children living with their murderous father . Shmuel has problems of his own; his father has gone missing after those with whom he participated in a march did not return to the camp . Bruno decides to redeem himself by helping Shmuel find his father . The next day, Bruno, who is due to leave that afternoon, dons a striped prisoners' outfit and a cap to cover his unshaven hair, and digs under the fence to join Shmuel in the search . Bruno soon discovers the true nature of the camp after seeing the many sick and weak - looking Jews, much to his shock . While searching, the boys are taken on a march with other inmates by Sonderkommandos . </P> <P> At the house, Gretel and Elsa discover Bruno's disappearance . After they discover the open window he went through Elsa bursts into Ralf's meeting to alert him that Bruno is missing . Ralf and his men mount a search . Led by a dog tracking Bruno's scent they find his discarded clothing outside the fence . Elsa and Gretel are following along behind . They enter the camp, looking for him; Bruno, Shmuel and the other inmates are stopped inside a changing room and are told to remove their clothes for a "shower". They are packed into a gas chamber, where Bruno and Shmuel hold each other's hands . A Schutzstaffel soldier pours some Zyklon B pellets inside, and the prisoners start panicking, yelling and banging on the metal door . When Ralf realises that a gassing is taking place, he cries out his son's name, and Elsa and Gretel fall to their knees in despair and mourn Bruno .
