Mung Ka-Ka (Sheren Tang), Cho Mei-Ngoh (Kiki Sheung) and Hilary Ding Mui-Hong (Cecilia Yip) are good friends and they are experts on how to raise a family. They teach Ko Wing-Kuen (David Chiang) how to raise his daughter and show him that it takes more than words to care for a child.
Along the way, they find out that their husbands might be secretly doing things behind their backs: Ka-Ka suspects her husband Joe Fong Yin-Jo (Michael Tse) is secretly pretending to be a woman, while in reality he is trying to pursue his goal of becoming a cross-dressing pop star.
Mei-Ngoh’s husband Ma Dai-Hap (Wilson Tsui) might be cheating on her with another woman.
Mui-Hong thinks her husband Bill Cheuk Kam-Biu (Derek Kwok) might be having an affair in which causes her to receive sexual diseases.
Shu Siu-Man (Leila Tong) just came back from America and suspects all three of them to have caused the death of her best friend Yoyo who is also Gam Shing-Tsun’s (Kenneth Ma) wife.
