"Banderas" is a real military action film, perhaps the first in Ukraine, based on real events. In September 2014, a terrorist attack was committed in the ATO zone on the "tip-off" of a saboteur - separatists destroyed a minibus, killing twelve adults and a child. It becomes known that the enemy informer is an employee of the Ukrainian army, at the same time it is revealed through radio interception that a colonel of the Russian GRU is waiting for the arrival of a colonel in this region.
