Historia Roja, czyli w ziemi lepiej słychać (2016)

In the spring of 1945, the commanding officer of the National Armed Forces in Mazowsze and older brother of 20-year-old Mieczyslaw Dziemieszkiewicz, is assassinated by Soviet soldiers. Mieczyslaw then joins the National Military Union. He becomes the commander of a partisan unit fighting for the next six years to free Poland from Soviet tyranny by terrorizing the UB and its collaborators. Communist authorities will do whatever it takes to track down the "enemy of the people's power."
