Crocodile keeper Zoe Jiang saves the second young master of the Guan Family by subduing a crocodile with a shovel, and is hired by the Guan family patriarch as Stepmom Zoe for three rebellious teens with an annual salary of 50 million. She adheres to a firm, no-nonsense parenting philosophy, using tough methods to discipline the unruly Guan children: she subdues the hot-tempered third child, exposes the scam targeting the love-obsessed fool second child, and stops the gloomy eldest child from going down a criminal path. As she falls in love with cold CEO Hugh Guan after their arranged marriage, she uses both firmness and sincerity to heal the three children's childhood trauma from their broken family, eventually gaining a complete, warm family.
