By content do you mean plot? In war-torn Poland, the Balicki family lives under Nazi occupation after the German invasion. Someone informs the Nazis that Joseph Balicki, a schoolteacher, has turned Adolf Hitler's picture to the wall; for this infraction, he is arrested and sent to Zakyna, a brutal work camp in the mountains of Southern Poland. Anxious to escape, he becomes sick, and it is eighteen months before he is well enough to put this plan into action. He manages to hit a guard with a small stone shot from a catapult, knocking him out and giving Joseph time to take his uniform and wear it; in this way, he is able to leave with the other guards. He hides in a cable car and is discovered by a Polish peasant; the peasant and his wife hide Joseph for a couple of weeks, at great danger to themselves.
