On the border of The United States and Mexico, a war is raging
that can never be won by conventional means. The drug cartels
are rampant. Their victims number in the tens of thousands. Men,
women and children are butchered in the most obscene ways
imaginable. Of all the cartels, the most violent is Los Zetas.
Made up of former Mexican special forces turned bad, they are
perhaps the most ruthless and highly trained criminals in the
world. Which is why only the most ruthless and highly trained
operatives can ever hope to be a match for them. Enter the
Regiment. When the CIA reaches out to the British military for
help, SAS legend Danny Black and his team are despatched to give
the Zetas a taste of their own medicine. Working deniably and
under the radar, their mission is to bring death and mayhem to
the cartel, and to coax out into the open their elusive leader
the iconic Z1.
