The documentary tells the story of Betar, which is a totally unknown Jewish youth organisation operating from the mid-20s until WWII both in Poland and all around the world. The organisation played an important role in history, even though it does not exist in literature or in people’s historical consciousness. Many members of Betar took an active part in rebuilding a Jewish country in Palestine and shaping its future. One of the members of the organisation was Menachem Begin, the Prime Minister of Israel in the years 1977-1983. The movie reveals the origins of the organisation, its core assumptions and its goals. Former group members talk about the meaning of Betar in their lives and, above all, how it changed them.
