Six lucky people are chosen to participate in a high-stakes Survivor-type game, Wolf Hunt, in which the winner takes home 10 million dollars. The rules dictate that the players conceal their assigned identities and vote out a suspected Wolf each night. The execution of the Wolf and its targeted prey will take place the following morning and this process will be repeated until the real Wolf is hunted down, the only variable being the fate of a prey either blessed or doomed by the Witch. As the grim reality of the situation begins to dawn on the players, schemes are being hatched and dark, sinister deeds are brewing. Unknown to all, this is a game turned horror tale where no one can win and all losers pay a heavy price.

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.
