Ten years ago, the Hale Family was mysteriously massacred, and Kael Hale barely escaped with his life. Ten years later, Kael is a top overseas mercenary codenamed 'Eagle'. He returns to his home country to track down his enemies, and infiltrates the side of corporate tycoon heiress Serena Sterling under a fake identity. One day, he is tasked with protecting Serena on a vacation trip to a mysterious island. When he boards the private plane, he can't help but smile. On this exclusive private jet bound for the mysterious island, there is his former fiancee who broke off their engagement and humiliated him after the Hale family massacre, relatives who refused to help him and mocked him back then, and his supervisor who has always picked on and made things difficult for him. Every single person he holds a grudge against, every person he has a score to settle with, has all coincidentally boarded this same plane.
