Zionists without Borders tells the story of the Halutz movement in Poland and its role in helping the Labor movement rise to the leadership of the Zionist Movement in the interwar period. It describes the founding of a mass national and socialist movement, which changed the face of the Zionist map. The leaders of the Labor movement in Israel established strong ties with pioneers from Poland, thus making the Halutz a cross-border movement, connecting Jews by means of politics, nationalism and socialism.
