As a result of an explosion of a supersonic grenade, the special-forces operative Taras Cherny “plunges” into ancient Sparta.

Taras, who looks very much like the dead Spartan Gysandor, is taken for one of their own. And the special-forces operative must prove that he has the right to be called a true Spartan.
