Just then, a woman named Ruth approached Craig and invited him to join a mercenary. It turns out that there is a small island called Snake Island in the waters near Eastern Europe, and no one knows where it really belongs, but not long ago, the evil Colonel Lupo (Gennadi Vengerov) occupied the island, and his men kept a group of money-minded and bloodthirsty villains, who arbitrarily grabbed the island's resources, killed innocent people, and did everything evil. To this end, several tycoons funded the purchase of arms and hired mercenaries to land on Snake Island to overthrow Lubo's tyranny. Craig will embark on a bloody journey with a group of experts. This film is based on the American war game of the same name.
