While on an expedition to discover the ancient secret of the Pills of Eternity, Professor Lin mysteriously disappears. His notebook survives and is kept by his university colleague Professor Ivy Chan. Ivy believes
the clues to the secret lie engraved on 2 stone tablets.

Helped by her two adopted daughters Mandy and Georgia, Ivy decides to mount an expedition to the remote border area between India and China in an effort to discover the whereabouts of the UNDISCOVERED TOMB where the Pills of Eternity are thought to have been hidden.

Meanwhile, the statue containing the first tablet is sold in an auction to a wealthy collector, Michael Lui. Ivy tries to borrow the tablet for her research. However, Michael's home is raided by the Wild Wolves who
want to use the tablets for their own evil ends. Luckily the attack fails and Michael agrees to let Ivy use the tablet but insists that he join the expedition.

Mandy and Georgia have set off in advance to try to find the second tablet. On their way, they meet up with a young local boy, nicknamed 'The Kid', who acts as a guide to the two girls. TheyÕve also run into a
young man, Steve, and the 4 end up travelling together. Mandy has fallen for Steve but Georgia feels that Steve's presence is more than just coincidence.

Ivy and Michael are following at some distance behind. However, the two are suddenly attacked by the Wild Wolves and Michael is killed. Ivy escapes into the forest. In the forest, Mandy, Georgia, Steve and The Kid come across a shrine where they find the second tablet. But the shrine is guarded by a tribe of natives who chase after the four to try to recover their sacred treasure. Eventually the four manage to escape with the second tablet. With the two tablets now in her possession, Ivy leads the group onwards towards their goal.
