Lara's father, before he died, was interested in something called The Triangle of Light, an object which had the ability to control time. But the ancient people misused it and it was split in two and the pieces scattered at opposite ends of the Earth. Every few thousand years there is a complete planetary alignment (ie everythiny - Pluto, Mars etc. is in line) and the pieces can be found. One day Lara hears a clock ticking and discovers it has been left by her father. She travels through tombs and outsmarts Alex and gets the first piece, while Manfred Powell tries to get it off her. Then she travels to the Arctic wastes to get the second piece, after discovering her father was in the cult group Illuminati.
