On the night before Yuet's wedding, best friends Nam and Yuet recall their time together in school, when they shared a relationship that was more than friendship, but also perhaps not quite love.

During a diamond heist, one of the security escorts steals the diamonds and flees. Fellow security escorts Yau Shing and Jelly are forced to help the robber track down the diamond. Tracking the diamonds, they stumble into a secluded village. While they clash with the weird villagers, the three men suspect that they are being haunted by a female ghost.
