Black Wolf(1972)

Black Wolf is a Cold War thriller set in the Bohemian Forest, where border guards Kucera and Stencl patrol the frontier between Czechoslovakia and Germany. When the unit's dog Líza catches the scent of a mysterious animal on the German side and breaks free, chaos erupts. A firefight ensues, leaving both soldiers wounded and an unidentified female agent dead. As investigators work to identify the woman, they discover she had local connections—yet no one in the nearby villages will admit to knowing her. The film unfolds as a tense mystery, blending espionage intrigue with the paranoia of a divided nation, where trust is a luxury no one can afford.
