It is said that "There is no fear in love; but perfect love casts out fear......". For most couples, keeping their romance alive is nothing more than an ordinary life, but for newlywed MOK TAI-HUNG (Eddie Cheung), a senior social worker, and LAM CHING-YI (Sharon Chan), a sex therapist, it is indeed very challenging. Despite their professional expertise and the nature of work that is to help people, they are too embarrassed to talk about the fact that their own sex life is constantly interrupted due to lack of privacy living with their extended family. This leads to a series of challenges that the other couples surrounding them face in forming and sustaining intimate relationships. They include neat freak and introvert MOK SIU-TO (Elena Kong) and her middle-aged boyfriend KAM CHEONG (Louis Yuen), May-December couple LIU CHUN-CHEONG (Hui Shiu Hung) and TONG TIM-TIM (Siu Po), as well as teacher TO TAK-KEI (Sammy Sum) and his sexaholic girlfriend CHUNG YING-MAN (Grace Wong). How are they going to break taboos to embrace a revolutionary concept of love?
