In a small French village during the German occupation of World War I, a group of German soldiers encounters a series of unexpected events that disrupt their monotonous routine. Led by the arrogant Lieutenant Fifi, these men enjoy life in the countryside, despite the hostility they feel from the locals. One of the village girls, a beautiful and determined young woman named Thérèse, becomes the target of Fifi's whims, who sees her as an object of conquest.
However, Thérèse is not an ordinary young woman; she possesses an indomitable spirit and a strong connection to her compatriots who resent the occupation. When the opportunity for revenge presents itself, she devises a plan to humiliate Fifi and his men, seeing this not only as a form of resistance but also as a way to restore her village's dignity. With a mix of cunning and bravery, Thérèse becomes the central figure in a story where love, pride, and betrayal intertwine.
As events unfold, the tension between the German soldiers and the locals escalates, culminating in a climax that changes the course of their lives. The film is a powerful tale of resistance, sacrifice, and the struggle for freedom, illustrating how the strength of a woman can challenge the most brutal oppression in times of war.
