An unexpected pregnancy catches couple TONG TIM-YEE (Ali Lee) and IP CHI-TING (Lai Lok Yi) off guard. They depend on their mothers for baby-sitting, but conflict ensues when the in-laws' parenting skills are poles apart. The emotionally wrought and physically challenging experience of caring for their baby girl 24/7 leaves them no other choice but to hire an experienced confinement nanny, WONG KAI-MIU (Griselda Yeung), to help them. The arrival of her newborn forces TIM-YEE to give up her fashion career; whereas CHI-TING has to say goodbye to his relaxing and enjoyable nightlife. In order to spend more time to look after her daughter, TIM-YEE changes her career to take over a post-natal care agency. With KAI-MIU pulling a few strings, TIM-YEE gets to know many expectant couples and nannies. In her role as a new mom, she is struck with a newfound appreciation, but feels like she and her husband CHI-TING are growing apart. On top of that, she even suspects that he has an affair with his coworker bartender HUI CHING (Samantha Ko). Surprisingly, CHI-TING captivates the internet after bravely saving a child in an accident, and is dubbed the "greatest dad" ever, which makes the agency a childcare KOL, turning things upside down.
