The young warrior Igor always wanted to be like his adopted brother Zakhar, who is five years older than him. Even as a child, Zakhar saved the young man from inevitable death, and since then Igor has been unsuccessfully trying to return the Debt of Life to his brother-brother. And so, during the very first raid, the young warrior has a chance to do this: a convoy carrying ammunition from Strogino to the Kremlin is attacked by a pack of neos. Evil mutants destroy the squad, take the cargo, and Zakhar disappears without a trace. Will Igor be able to go through all the trials, find the stolen cargo and save his brother-in-law? Alone - unlikely. But, fortunately, a very unusual assistant comes to his rescue...
