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.
