A group led by Sergey Pastukhov is tasked with finding and neutralizing a secret superweapon that Islamic terrorists are hunting. But very soon the mercenaries begin to understand that the matter is not really about the secret weapon—maybe it doesn’t even exist; instead, large money and big politics are involved here. They are only meant to serve as pawns. Can real professionals accept that? Pastukhov and his friends plunge into a brutal fight not only with terrorists, but also with the lies that have entangled the “Mercury” project.
