When an attack on the Kingsman headquarters takes place and a new villain rises, Eggsy and Merlin are forced to work together with the American agency known as the Statesman to save the world.

The story of a super-secret spy organization that recruits an unrefined but promising street kid into the agency's ultra-competitive training program just as a global threat emerges from a twisted tech genius.

Before Charles Xavier and Erik Lensherr took the names Professor X and Magneto, they were two young men discovering their powers for the first time. Before they were arch-enemies, they were closest of friends, working together with other mutants (some familiar, some new), to stop the greatest threat the world has ever known.
