Lieutenant Apostol Bologa, a Romanian serving within the Austro-Hungarian Army, votes to sentence Second Lieutenant Svoboda to death. Svoboda, a Czech officer, is found guilty of desertion and is executed by hanging, a verdict that sets off a chain reaction of doubt and moral reflection in Bologa. While Svoboda awaits his execution, Bologa encounters Captain Klapka, a fellow Czech officer who has recently transferred from the Italian front to the same regiment. Together with the rest of the unit, they witness Svoboda’s death, an event that leaves a lasting mark on Bologa and unsettles his sense of allegiance within a multinational army.
The execution becomes a catalyst for Bologa’s unease about the empire he serves. The presence and influence of Captain Klapka, along with other minority soldiers in the Austro-Hungarian ranks, plant seeds of doubt about national identity, loyalty, and the value of life beyond imperial commands. As Bologa wrestles with these doubts, the tension surrounding him intensifies, forcing him to confront questions about guilt, duty, and the human cost of war.
At a formal dinner with his fellow officers, Bologa faces pointed criticism, notably from Captain Cervenko, who embodies Tolstoyan nonviolence and religious scruples. Cervenko argues that agony is a necessary condition for growth in love, while Bologa’s involvement in Svoboda’s execution casts him under a harsh spotlight. The debate grows sharp and philosophical, with a few officers offering caustic commentary about how theory clashes with the brutal realities of battle. One colleague jokes about a dream of a united Internationale, only to mock the notion by pointing out how Austria-Hungary already stages a fractured solidarity among diverse subjects who fight side by side in an imperial army.
After that tense evening, the two officers retreat to their quarters. Bologa, unsettled and morally rattled, keeps repeating that Svoboda was innocent. Klapka responds with a cold pragmatism, suggesting that their shared guilt extends beyond the specific case before them. The room is suddenly lit by a rotating beam of light from outside, a strange omen that Klapka interprets as a reminder that any light—no matter its origin—can be welcome in the surrounding darkness.
The weight of what he has witnessed presses hard on Bologa as he is ordered to judge twelve Romanian peasants accused of espionage. Unable to bear the prospect of condemning more of his compatriots, he makes the fateful decision to desert toward the Romanian lines. His attempt is thwarted, and he is captured and sentenced to hang. On his way to the jail, he passes the forest where the twelve Romanians he was meant to condemn now hang from the trees, a stark image that seals his crisis of conscience.
In prison, those closest to him who survived the ordeal visit. Klapka pleads with him to claim that he simply got lost, but Bologa rejects the plea and refuses to absolve himself of responsibility. The story culminates in a solitary, unbearable realization: Apostol Bologa can no longer live within the system that has demanded so much from him, torn between his sense of duty, his humanity, and the crushing consequences of his choices. The film tracks a quiet tragedy of conscience in the face of institutional power, exploring how individual integrity can collide with collective allegiance and the costs of remaining true to one's own moral compass.
