The movie starts off with a man, named Schlomo (Lionel Abelanski), running crazily through a forest, with his voice playing in the background, saying that he has seen the horror of the Nazis in a nearby town, and he must tell the others. Once he gets into town, he informs the rabbi, and together they run through the town and once they have got enough people together, they hold a town meeting. At first, many of the men do not believe the horrors they are being told, and many criticize Schlomo, for he is the town lunatic, and who could possibly believe him? But the rabbi believes him, and then they try to tackle the problem of the coming terrors. Amidst the pondering and the arguing, Schlomo suggests that they build a train, so they can escape by deporting themselves. Some of their members pretend to be Nazis in order to ostensibly transport them to a concentration camp, when in reality, they are going to Palestine via Russia. Thus the Train of Life is born.
