Don't Open the Door (2016)

A township in Yunnan province, southern China, the present day, 13th of the month. Yang Hao, young boss of Wumiaohui Inn, invites six of his staff to dinner in one of the restaurant's private rooms to meet his friend Peter, who's just returned from abroad. Yang Hao has a mutually convenient sexual relationship with one of his waitresses, Naonao, but is openly trying to seduce another, Xiaofei, who isn't interested. Xiaofei is upset by the disappearance of a colleague, Penny, who hasn't come to work for a month; the police have no leads so far. Also at the dinner are head cook Xianye, his young assistants Fatty and Huazi, and manageress Liu Bingbing. Huazi and Xiaofei are childhood friends. The dinner goes awkwardly, with no one liking the offensive Peter, who retires early. Xiaofei drinks heavily to avoid the attentions of Yang Hao, who then has sex with Naonao in the toilets. Afterwards, Naonao visits private room A113 - which is supposedly haunted on the 13th of every month.
