During the Second World War, a dangerous “Cassandra” virus was created in Nazi Germany, which kills all living things within 24 hours. The Germans did not have time to use the weapons for their intended purpose - during the rapid offensive, the bunker where the safes with the virus were kept ended up behind Allied lines. It was not possible to find out his exact location later; it was only known that he was located somewhere on the coast of the Netherlands. Over time, they forgot about “Cassandra.” And after a while, two brothers Julian and Marius Wild found a secret bunker. They are blackmailing the United States and NATO and demanding $5 million in exchange for the virus, otherwise "Cassandra" will either be sold to the "enemies of the West" or released. The best operative of Department "K" Sam Darell is already in a hurry to the Netherlands, "Cassandra" opens an account with his the first victims, and those to whom it previously belonged also begin to hunt for the virus.
