Many people are hiding in the Volga floodplains. They ended up there for different reasons, but they trade in the same thing - poaching and piracy. There are alarming news about events in the lower reaches of the Volga: either an armed attack was carried out on the yacht of a local oligarch, or a container ship with expensive cargo disappeared... It is very difficult to discover a pirate nest in the floodplains, and law enforcement agencies are not too eager to deal with this problem. Everything was decided by an almost accidental meeting of pirates with the former commander of the air assault battalion Boris Rublev. The former soldier (and now the captain of the ship) invited Combat to relax for a couple of days on a cruise ship. Boris agreed. The ship was attacked by pirates... The intervention of the Battalion Commander not only stopped the pirate showdowns and stopped the pirate raids, but also lifted the curtain on many secrets of the criminal caviar business.
