Four Ukrainian saboteurs are given a mission to carry out on Russian territory. Nepiypivo, Svyatosha, Apollon, and Tarasiy are among the first to take the war to enemy territory. After this combat mission, they become legends of the Russian-Ukrainian war. This is a story about those for whom war has become a form of service. About faith that guides in the darkness. About a choice that not everyone is capable of making. About brotherhood and "Brotherhood." And about the four who forever changed the rules of war with Moscow.
