In a remote part of the taiga, a plane crash occurs. On board there was valuable cargo, the details of which are known only to a few. It’s known only that the cargo is connected to a new secret deposit of metals from the platinum group. To carry out a search operation, a team is sent to the crash site: Daria Pogodina, a doctor from the Ministry of Emergency Situations, and Boris Lipkin, a special forces operative. The identities of the other team members remain unknown. However, the search mission faces serious difficulties: the rescuers begin to die under mysterious circumstances.
