在某公司任职的杨天乐（方力申 饰），某天早晨接到老同学韩阳的电话，邀请大家到一处位于荒郊野岭的老别墅聚会。约定的当天，天乐乘坐蒋为平的车来到别墅，老同学们三三两两到来。在这片幽静的角落，他们有说有笑，好不吵闹。谁知当聚会正在高超之际，一场暴雨突然而至，搅扰了众人的雅兴。当大家躲在房间里生闷气的时候，韩阳突然带来了令众人都意想不到的人物林悦。十五年前，这群好同学相约去白龙潭游玩，夜晚他们因某事请碟仙，结果导致林悦被莫名之火严重烧伤。久未见面的林悦宛若天仙，脸上全然不见烧伤的痕迹。

　　夜幕降临，当众人正尽享快乐的时候，蒋为平竟意外死亡。以此为契机，众人被卷入可怕的黑暗之中……

Yang Tianle receives a phone call from his old classmate Han Yang one morning, inviting everyone to a meeting at an old villa in the wilderness. The same day, Yang drives with Jiang Weiping to the villa, where the old classmates come in twos and threes. In this quiet corner, they are talking and laughing, generally being noisy. Just as the party is going well, a sudden heavy rain hits, disturbing the crowd of Masin. While they are hid in the room sulking, Han Yang suddenly surprises everyone with the unexpected guest Lin Yue. Fifteen years ago, these good classmates went to White Dragon Pool to play at night. When they played Ouija, Lin Yue was severely burned by an inexplicable fire. Weirdly though, his face now has no signs of burns. As night falls, when everyone is enjoying the time, Jiang Weiping unexpectedly dies. With this as an opportunity, everyone becomes involved in the terrible darkness.
