The legendary thief marries into the Xu family, thus starting a battle of wits and will with a stone-faced inspector. Caught in a cat-and-mouse game, the two natural enemies learn to become husband and wife. The real identity of the "willow thief" is Liu Rong. Thirteen years ago, she was rescued by Lord Su from the great floods in the South. In order to repay him, Liu Rong pretends to be his daughter, Su Jin Zhen, and marries Xu Mu Chen. Under Lord Su's instructions, she must infiltrate the Xu manor in order to find a jade pendant. From the start, neither spouse gave any thought to their sham of a marriage. On the surface, Liu Rong is a gentle and considerate wife. By night, she is a notorious bandit.
