Ostatnie Pietro plot
A man's paranoia becomes overwhelming when he accidentally learns that the military unit he serves is entangled in a mysterious criminal affair. Around the same time, his wife's ex-lover also appears in the apparently quiet town. And to make matters worse, his son is beaten up at school. The man, an experienced Polish army captain named Derczynski, slowly begins to lose his mind. Hoping to protect himself and his loved ones, he and his family barricade themselves in their own cramped apartment on the last floor of the building.
