After Lara Croft returns from a hunting trip in the Himalayas, she is contacted by Jacqueline Natla, a conniving businesswoman who convinces Lara to recover a mysterious artifact from the tomb of Qualopec in Peru. Wasting no time, Lara sets out on her quest to find one of the three pieces of the ancient Atlantean Scion, a talisman of incredible power. However after discovering the fragment, things get ugly when Lara finds herself face to face with one of Natla's hired goons. Using her cunning wits and athletic strength, Lara escapes.

As she delves into the reasons why Natla would double-cross her, she uncovers a mystery that reaches back before the dawn of recorded time to the treachery that destroyed the Atlantean civilization and the disasters that struck the world when it fell.
