The documentary by Alexander Nanau and Liviu Tofan is developed within the Discovery Campus Masterschool, specialized in project development of documentary films for an international audience. The project will be pitched at the end of October in Leipzig, where the final session of the Masterschool will take place. On completion of the Discovery Campus Masterschool, the participants pitch their projects to more than 50 high-ranking commissioning editors and distributors. "It’s a matter of life and death" ("One last tango") aims to be a real life thriller from the time of the Cold War, a film which tells about the clash between ideals and the cynicism of politics, and about the drama of its victims.
