A young man is sitting in a darkened study. In a telephone conversation he learns that his invention has not been accepted for production in a test series. A pistol shot rings out. The young man is in an almost empty tiled room where an old bearded man is playing with a dog. The old man introduces himself as Pavlov, head of the admissions department for inventors. He informs the young man named Jim Jefferson about the result of the proceeding of the commission. Originally Jefferson was supposed to be housed in Pavilion Z, designed for the authors of inventions that have helped humankind to engage in mutual destruction. Finally, however, he is allowed to continue his research in no. 2573 in Pavilion C. In the room are men diverting themselves in various ways. Jefferson is consulting one of them about his calculations. Max Born is playing dominos. Alfred Nobel is to one side, thinking. Robert Oppenheimer is playing hopscotch and invites Jim to join in... Jefferson is back sitting in his study. When the telephone rings, he doesn't pick it up, but thinks to himself.
