1912, Russia is pregnant with revolution. Smart, patriotic gendarmes understand the situation perfectly and are literally biting their elbows from powerlessness to change anything. No less patriotic revolutionaries have no doubts and are confident that they will become the harbingers of a bright future. And at this moment Bulgaria enters into war with Turkey. Wartime is an excellent opportunity to settle scores with old enemies. The Odessa gendarme department is preparing a cynical provocation with the liquidation of the hated "Socialist Revolutionaries". And the talented pilot Timofey Efimov goes to war. He goes not of his own free will, but forced by blackmail of the gendarmes, not even suspecting that this is how they save him from inevitable death and hope to return the young man who recently joined the Socialist Revolutionary Party to the true path. But the medicine is worse than the disease, and war is too dirty.
