It's the summer of 1941 and the Nazis are depleting entire villages of Jews in eastern Europe. Upon learning this, Shlomo (LIONEL ABELANSKI), the inhabitant of one such village, races home to inform the village's "wise men," including the local rabbi (CLEMENT HARARI) and accountant, Yankele (BRUNO ABRAHAM-KREMER), of such atrocities.
Concerned about how to react to such news and what step they should next take, Shlomo, known as the village idiot, suggests that they deport themselves from the town before the Germans do, acting as if they're headed for a concentration camp when in reality they'd be traveling to freedom. Although the idea is initially met with criticism, after no one else comes up with anything better, the wise men agree.
The only problem is that they don't have a way to get through German checkpoints without German soldiers onboard a train, and to make matters worse, they don't even have a train. Thus, the rabbi and the others choose a group of men to dress and act like Nazis, with Mordechai (RUFUS), to play the head officer.
Slowly acquiring and then fixing up freight cars and finally a locomotive for their train, the villagers set off on their trek to Palestine. Among the many villagers onboard is Esther (AGATHE DE LA FONTAINE), the town beauty who's in love with Mordechai's son, Sami (MIHAI CALIN), as well as Yossi (MICHAEL MULLER), a young man who believes himself a communist and is determined to convert the others.
As the villagers' train makes its way through the European countryside -- driven by a man who's never conducted a train before but is learning via a manual -- they must contend with several problems. They include a small group of resistance fighters who believe the "soldiers" to be real Germans, Yossi's protests and attempts at causing a communist uprising on board the train, Mordechai and his troops taking their role playing a bit too seriously, and finally real German units who stop the train at various points questioning their orders and destination.
