The series revolved around a solicitor Frances Mo (Carol Cheng) and her paralegal advisor Yu Lok-tin (Dayo Wong). The two characters go from loathing to loving each other by the end of the series, and eventually become a couple.
A large part of the series takes place in C.K. Law Firm where Frances and Lok work. Their relationship extends past the office as they both live in the same apartment which gives them more opportunities to cross paths.
Between avoiding the "spinster" label and creatively fighting trivial law suits, Frances uses her wit and class to outsmart her main rival, solicitor Alex Pao (Joseph Lee). In addition, Frances also has personal problems to deal with in the homefront such as getting used to her new younger stepmother, Yuen Yuen (Martha Yuan).
