Udd (Kerttisak Udomnak) and Yai (Nakhorn Silachai) are a gay couple who love cowboy films. They move from the city to a rural area that matches the backdrop from their favourite film, Brokeback Mountain, for a more intimate, rustic setting to their relationship. They buy an abandoned petrol station and look to settle down. Udd then finds that Yai is having an affair with Tangmo (Achita Sikamana), a local woman who has a lesbian lover, Jenny (Supassra Ruangwong). Neither Yai nor Tangmo are aware of either of their sexual histories, but Udd discovers the affair and plans murder out of revenge. However, they are oblivious to the fact that their petrol station is already haunted by some scary spirits.
