Mehdi Huseynzade a.k.a. Mihajlo is the most wanted guerrilla in Yugoslavia and Trieste, moving undercover as a Wehrmacht officer to operate on the edge of danger. He pulls off a bold terror act in a restaurant packed with German officers, a calculated strike that showcases his nerve and resolve. The triumph is short-lived, however, as a spy named Carranti embedded within the guerrilla ranks wounds him, forcing a pause in his activities while he recovers. During this lull, Mihajlo tends to his wounds in relative quiet, discovers solace in painting, and dreams of a future homecoming to his homeland of Baku after the war.
As the manhunt tightens and the bounty rises, Mihajlo launches another audacious mission to secure a crucial food supply for the partisans, arranging to meet with a wealthy Italian businessman who can grease the wheels of resistance. The work is never solitary; Mihajlo relies on a trusted partner, Veselin, and a young woman named Anjelika. The trio navigates a delicate and dangerous balance, caught in a classic love triangle: Veselin loves Anjelika, Anjelika is drawn to Mihajlo, and Mihajlo, while moved by Anjelika’s presence, keeps his focus squarely on the mission and the work at hand.
During the next operation, Anjelika is briefly detained by the Germans, yet she manages to pass vital information to Mihajlo and Veselin. Armed with this intelligence, they complete a daring act: they explode a movie theater and take the lives of hundreds of German officers, all while weaving their escape under the cover of chaos. The scale of the retaliation only deepens the German pursuit, and Mihajlo soon finds himself in a tense encounter with Major Schulz. Pretending to be a humble, half-German, half-French painter named Auguste Kraus, Mihajlo demonstrates a surprising talent by rendering a portrait of Schulz. Convinced that he is merely a gifted painter, Schulz releases him, not suspecting the dangerous truth that Mihajlo and Kraus are one and the same.
Outside Schulz’s office, a chance meeting with Veselin escalates into immediate danger as German soldiers close in, forcing the two friends into a confrontation from which Veselin emerges mortally wounded, dying in Mihajlo’s arms. The blow shakes Mihajlo to his core and fuels a ruthless spiral of vengeance. Returning to the guerrilla camp, he receives the devastating news that Anjelika has been murdered, a loss that hardens his resolve and intensifies his retaliatory campaign against the occupiers, driving him to blow up more hotels and facilities.
Mihajlo’s path eventually leads him to Carranti once more, where he delivers a fatal blow and leaves with a suitcase of money. Chased by German forces, he makes it to the village of Veselin’s father, where Schulz and his troops converge on the locals, demanding information about Mihajlo’s whereabouts. The villagers stand firm and refuse to betray him, and Mihajlo chooses to face the danger rather than risk endangering the townspeople. In a tense standoff, Schulz realizes that Mihajlo and Kraus are the same person, but the revelation comes too late to save him. Mihajlo kills Schulz, but he is mortally wounded by the German soldiers who close in. In his final moments, with memory of home and the longing to return to Baku crossing his mind, a detonating bomb strapped to him destroys the approaching soldiers, sealing his fate in a last, fateful act.
