After being separated for years, two childhood best friends find themselves reunited. Adam and Enna are not alone, for they are being hunted by a group of twelve trained killers known as the Zodiac, whose goal is to wipe out all of those who are blessed with inhuman abilities. These gifteds have little hope for the future, and their numbers are dwindling. After a prophetic vision, it is clear that Adam is their only hope for survival. However, things are not nearly as simple as they seem, for Adam's own twin brother, Kenny, turns out to be one of the leaders within the Zodiac group.
