The youngest daughter of the Shen family appears cute, naive, and lazy, solely wishing to sneak a bite of spicy hot pot. In reality, she wields four astonishing secret identities: Zero, the number one dark web hacker; Zhiqiu, the surgical sage; Nightingale, the legendary racing god; and S, the Wall Street financial crocodile. Her four older brothers are wholeheartedly protective of their younger sister, strictly guarding her against eating takeout and suffering grievances, yet they do not know that the legendary big shot they are desperately tracking is none of-the younger sister being watched over. As the arch-rival Huo family presses in step by step and multiple identities are unveiled layer by layer, a game of love and hatred thereby unfolds.
