The capital's business empire has undercurrents surging. Zhijintang patron Jiang Nian, to experience all walks of life, goes under an assumed name to work as a security guard in a residential compound. Five years ago, she supported her impoverished fiancé Lin Qingyuan to rise, but suffered his betrayal and cancellation of the marriage, turning instead to collude with step-sister Jiang Rou. On the day of the wedding, Jiang Nian publicly exposes her identity, making everyone who bullied her pay the price, and ties the knot with the truly kind Chen family young master Chen Ziyan, taking charge of the commercial lifeline and guarding the home and country.
