At the outpost of the Tenginsky regiment, fate brought together five young officers: Captain Rajewski, camera junker Nikolai Annensky, a duelist, a gambler and a wonderful swordsman Alexander Shulenin, a young officer Fyodor Chistyakov and lieutenant Vladimir Baumgarten exiled to the Caucasus for Duel Golitsyn's murder. They are destined to play a grandiose, tangled play to find the true culprit of the murder of Prince Golitsyn. One way or another, everyone was drawn into this story, everyone - both the perpetrators and the executioners. To cut this "Gordian knot", the drama participants decide to arrange a "carousel" - a kind of duel for five, where there will be no winner.
