On Liang's 18th birthday, she is unable to celebrate with her boyfriend because she has to babysit her irresponsible brother's baby. Refusing to lose her adolescence through a responsibility that shouldn't be hers, Liang sets out on a “mission to reclaim youth” as she tries to return this crying bundle of joy to her brother.

The director tells an unconventional coming-of-age story with a unique feminine perspective. Through a teenage girl's day-long journey with a baby, we follow a teenager who is left without choice and can only resort to her instincts to set things right when her family mistreat her. The film's comic moments are richly-flavored with Taiwanese local culture and campy humor, such as a granny sitting at a breakfast table who can only eat when someone brings her dentures. At the same time, through keen observation, the director vividly and earnestly portrays her characters.
