True to the title, the Swedish Oscar winner will indeed be raiding some tombs in some far-flung mythical island. She's not just doing it for the heady thrill of danger, but to track down her father who disappeared at sea when she was just a teenager.
The official synopsis from Warner Bros. offers more context:
Now a young woman of 21 without any real focus or purpose, Lara navigates the chaotic streets of trendy East London as a bike courier, barely making the rent. Determined to forge her own path, she refuses to take the reins of her father’s global empire just as staunchly as she rejects the idea that he’s truly gone. Advised to face the facts and move forward after seven years without him, even Lara can’t understand what drives her to finally solve the puzzle of his mysterious death.
Leaving everything she knows behind, Lara goes in search of her dad’s last-known destination: a fabled tomb on a mythical island that might be somewhere off the coast of Japan. But her mission will not be an easy one; just reaching the island will be extremely treacherous. Suddenly, the stakes couldn’t be higher for Lara, who—against the odds and armed with only her sharp mind, blind faith and inherently stubborn spirit—must learn to push herself beyond her limits as she journeys into the unknown. If she survives this perilous adventure, it could be the making of her, earning her the name tomb raider.
Vikander, who won the Oscar for Best Supporting Actress for her work in 2015's The Danish Girl, appears to be a worthy successor to Angelina Jolie, who played Lara Croft in Tomb Raider in 2001 and its sequel The Cradle of Life in 2003.
Tomb Raider hits theaters on March 16, 2018.
