Full-time mother Hong Nga-yu (Eliza Sam) and her husband Yau Tsai-shan (Kenneth Ma) have a two-year-old daughter, Yau Ri-tong. The family lives with Yau's parents, Hong Lok (Lee Kwok-lun) and Fong Chor-kiu (Kung Tsz-yan), and is under great pressure. Tsai-shan plots to break away from Chor-kiu's control, but his parents, Yau Tai-lang (Ng Tai-yun) and Kam Mei-huan (Sheung Tin-ngee), keep making trouble, which makes Tsai-shan always at a disadvantage. Yau and Tsai-shan have constant friction over the division of parenting duties, and Yau is determined to go out to work... At the same time, new and old grudges between the "four elders" arise one after another, and Shan's younger brother Yau Tsai-fung (Ng Yip-kwan) and his wife Cheung Pik-tzu (Huang Wenyi), Yau's cousin Ye Fan (Chen Ziyi) and her husband Kwan Chi-chung (Cheung Wing-hong), also face various contradictions and difficulties in parenting life, which highlight that children are an opportunity for parents to learn and grow throughout their lives.
