Black Widow (2021)

In 1995, super-soldier Alexei Shostakov and Black Widow Melina Vostokoff, Russian undercover agents, pose as a family in Ohio with their surrogate daughters Natasha Romanoff and Yelena Belova. After finishing their mission to steal S.H.I.E.L.D. intel, they escape to Cuba and rendezvous with their boss, General Dreykov, who has Romanoff and Belova taken to the Red Room for training. Years pass, during which Shostakov is imprisoned in Russia while Romanoff defects to S.H.I.E.L.D. after bombing Dreykov’s Budapest office, apparently killing him and his young daughter Antonia.

In 2016, Romanoff is a fugitive for violating the Sokovia Accords. She escapes from U.S. Secretary of State Thaddeus Ross and flees to a safehouse in Norway supplied by Rick Mason. Meanwhile, Belova kills a rogue former Black Widow but comes in contact with a synthetic gas that neutralizes the Red Room’s chemical mind-control agent. Belova sends antidote vials to Romanoff, hoping she will send the Avengers to free the other Widows. When Romanoff unknowingly drives off with the vials, Taskmaster attacks her seeking them. Romanoff manages to escape Taskmaster and realizes that they came from Belova. The two reunite in Budapest. Romanoff learns Dreykov is alive and the Red Room is still active. Shortly after, Black Widows attack them. Romanoff and Belova evade them and Taskmaster before meeting Mason, who supplies them with a helicopter.
