Based on true events, a Hong Kong teenage girl’s first day out of juvenile detention center takes an unexpected turn.

Ting and her friends go to Mui Wo where they see cows freely walking around. Someone appears and reminds them not to disturb the cows. The next day comes the news that seven cows were killed in a car accident at Mui Wo, which catches Ting and her friends’ attention. Ting starts a fundraising campaign hoping to build a cows’ shelter but is taken as an act to trick people’s money. The disheartened situation brings Ting to revisit the site, where she meets Sunset, the cow caretaker whom they have met before. She eventually develops a sense of responsibility to protect the cows when one day Sunset asks her to inherit the post of caretaker from him.

At some point in life an age-old question will inevitably crop up: Do we swim against the tide or go with the flow? The band, Against the Tide, was doomed before it even started. A year later, the songwriter is selling his soul to catchy pop tunes and commercial music, hitching his wagon to else’s grand schemes while being hitched by a young music devotee; the bassist is venturing north across the border; the drummer is working as an insurance agent and all set for fatherhood. Before the factory building is demolished for a lucrative redevelopment scheme, the band members, bar one, return to their studio to clear out the place, contemplating making a final appearance for a farewell gig. The reunion takes place, albeit obliquely, each member putting their best foot forward to steer their own course.
