Young Master Xiao wants to find the green jade five-branched lamp in the tomb of a Han dynasty princess from Nanyang Commandery. He assembles a team that includes Liang Shangfei, an expert tomb raider, and Professor Li, an archaeologist. They excavate thirteen cenotaphs in succession. After entering the fourteenth tomb, strange events begin: the wooden walking stick used to guide them snaps, team members are slaughtered by an unknown force, and the group becomes trapped in a "ghost wall." They also encounter monsters that bewitch people's minds and the illusion of eerie green headlights. The group turns against itself, suffering heavy casualties as they face dangers such as the "Suspended Soul Staircase" and the "Burial Pit." At last, they find the green jade five-branched lamp in the tomb chamber. Its ghostly light triggers hallucinations, and Liang Shangfei mistakenly picks up a human bone, drawing the tomb's specters after him. Young Master Xiao and the others seize the chance to escape, while Liang Shangfei is left trapped in the tomb, losing both the treasure and his life.
