Retired dragon head Jiang Qiqiang has been selling fish for twenty years, while his daughter, fostered in a brother's family, is insulted and beaten. On the wedding day, son-in-law Zhang Yu is about to project secretly taken nude photos onto the giant screen, and Jiang Nian plunges to her death in despair. At that moment, his identity hidden for twenty years is finally revealed: a single phone call dissolves the Hongyi Society, a private plane lands, and men in black line up to pay respect. But his eyes are only on his daughter, and the killer of his wife, whom he has chased for twenty years, has actually been hiding in the shadows all along. This time, he will no longer endure.
