It is a story of Jewish artists who struggle with the WWII reality by the only means available to them which are music, theatre and film. They defend themselves from the Nazi repression by performing at cabaret shows organized in concentration camps and ghettos. In fact, they fought not only for life but also for their dignity. The movie includes recreations of the performances and shows the unique kind of humour and mockery, clear for the prisoners and incomprehensible for the guards and authorities.
