In a remote area near the border between India and China lies an Undiscovered Tomb. Two ancient stone tablets are said to hold the secret of the tomb and Ivy Chan, an archeologist, plans to find it. An expedition is arranged which includes her adopted daughter and a wealthy socialite called Michael Lui, the owner of one of the tablets. They encounter perilous conditions, hostile tribes, dangerous insects and animals as well as supernatural forces and a double-cross from inside the group.
