New addition to the MCU Yelena Belova (one of the most must-see rising stars today Florence Pugh) asks her estranged nonbiological sister Natasha Romanoff (the eponymous Black Widow reprised, presumably for one final time, by Scarlett Johansson in this interquel set sometime after Captain America: Civil War) what her story is.
The film then fast forwards to the present day; Natasha Romanoff (Scarlett Johansson) is being hunted by the U.S. government, and Thaddeus Ross (William Hurt) following the events of “Captain America: Civil War.” Now a fugitive, Romanoff is ten steps ahead of them, but more importantly, the echoes of this shattered family, traumatically torn from her at a young age, are still a painful wound that’s never properly healed or found closure.
As you'll surely recall, that was the year of Captain America: Civil War , in which the Cap and Tony Stark/Iron Man had a big falling out and Natasha disappeared.
Sure, there are references to the Avengers, and Black Widow's reintroduction makes more sense if you remember it's a prequel that takes place just after Captain America: Civil War.
Two decades later, Natasha Romanoff ( Scarlett Johansson ) faces the aftermath of her choices in Captain America: Civil War .
Taking place right after 2016’s Captain America: Civil War , Black Widow sees the titular Avenger on the run and reconnecting with her past.
