The story delves into Lara's history, beginning with her life-altering plane crash in the Himalayas. 

In Crystal Dynamics' version, this happens at the start of the game in flashback. Lara is just a young girl at the time, and her mother survives the crash along with her, only to vanish under mysterious circumstances.

Throughout the game, Lara searches for the pieces of the fabled sword, Excalibur, which she hopes will help her get to the bottom of her mother's disappearance. On the way, she crosses paths with Amanda Evert, an old friend Lara had long believed to be dead but who turns out to be seeking the sword for her own reasons.
