Li Shengtang, a financial tycoon at the top of the world, is admired by all. His reckless son marries the martial arts alliance leader’s daughter, while his strong-willed daughter weds into the powerful Zhao family. But Li knows that once he's gone, those who praise him will turn against his children and seize his fortune. To test their loyalty, he fakes his death with his butler’s help—terminal illness on day one, sudden death on day two, and a grand funeral on day three. As he lies on his ‘deathbed,’ chaos erupts over his inheritance. Then, Bai Bing, a warrior he once helped, suddenly proposes, offering to marry him even for just one day. His in-laws suspect a scheme and fiercely oppose, but Li insists. Assassins lurk, media stirs trouble, and on their wedding day, as Bai Bing steps forward, Li 'dies' on stage. The world believes he's gone, but only the butler knows—the real game has just begun.
