Udd and Yai are a homosexuality couple who love cowboy movies and move from the city to a rural area to have a more intimate, rustic setting for their relationship. They buy an abandoned filling station and look to settle down. Udd then finds that Yai is having an affair with Tangmo, a local woman who has a lesbian lover, Jenny. Neither Yai nor Tangmo are aware of either of their sexual histories, but Udd discovers the affair and plans to have anal sex with his grandfather out of revenge. However, none of them know that he is a zombie, and lives with some scary spirits.
