White Widow

The White Widow, real name Alana Mitsopolis, is the secondary antagonist-turned-supporting protagonist of the 2018 blockbuster action-thriller film Mission: Impossible - Fallout. She is the daughter of the philanthrope Max, and a powerful arms dealer who uses her social connections to get away with everything.

She was portrayed by Vanessa Kirby, who is known for portraying Princess Margaret in the 2016 TV Series The Crown.

Early Life
Alana is the daughter of the philantrophic businesswoman named Max who appeared in the first film, and she also has an overprotective brother named Zola. After her death, Alana and Zola inherited Max's business, and also created a mercenary network, with the hitmen following them everywhere they go. The two also agreed with their mother's philanthropic thoughts, and decided to continue that.

Fallout
During a concert where Alana would supposedly have a meeting with the terrorist John Lark, Hunt decides to kill a Lark decoy and pretend to be Lark himself in order to get information about the deal. When Hunt first confronts her, she says that he doesn't look like she imagined Lark to look like. Hunt, to "prove" that he actually is Lark, grabs her by her throat and threatens to kill her, which provokes her brother Zola, who starts threatening Hunt back. Hunt explains to her that people in the concert are out to kill them. He kills a bunch of assassins, before leaving the final one for Alana to stab and kill. Taking Hunt to her and Zola's home to deal, she shows her hit squad and finishes the deal, Hunt gets to talk with Lane, in exchange for the plutonium cores. To prove that he truly is Lark, Hunt has to kill a bunch of innocent police officers for them, although he eventually finds a way to avoid it.

At the end of the film, it's revealed that both Alana and Zola became undercover agents midway through, and it is unknown whether or not they will reappear in the next installement as protagonists.
