Ten years ago, the Qin family suffered a mysterious massacre, and Qin Xiao narrowly escaped with his life. Ten years later, Qin Xiao is a top overseas mercenary, having returned to China to seek out his enemies, disguising his identity by staying by Lin Yurou's side. Today, he is tasked with protecting Lin Yurou on a vacation to a mysterious island, and when he appeared on the airplane, he couldn't help but smile. A special aristocratic charter flight heading straight to the mysterious island for a vacation carried his ex-fiancée who broke off their engagement and humiliated him after the Qin family massacre, relatives who refused to help him and mocked him when he was left for dead, and supervisors who constantly squeezed and gave him a hard time. In this lifetime, all the people he held grudges against, harbored hatred for, or simply couldn't stand coincidentally ended up on this very plane.
