On the day of Ning Haotian (Ken Chang)'s marriage, his fiancé Xiang Xueyin (Tang Yixin) eloped with his junior, An Qiusheng (Lv Xingyu).

Xueyin gives birth to a baby girl named An Ruohuan (Tiffany Tang), who carries a unique scent on her body.

An Qiusheng misunderstood and thought that Bai Songxian (Yang Mingna) had let his whereabouts be known to Ning Haotian, who had wanted to exact revenge on him for eloping with his fiancé.

Twelve years later, Yichen was tasked to investigate the case of missing young ladies in the Mo Wang province.

However, Huizi's father Tai Lang (Li Yaojing) schemes to steal the Chinese traditional artistic fragrance secrets, and plans to conquer Mo Wang Province.
