Black Widow is the twenty-fourth film in the Marvel Cinematic Universe focusing on Natasha Romanoff/Black Widow after Captain America: Civil War and before Avengers: Infinity War with some unfinished business and facing her past with a reunion of her family.
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.
Romanoff and Belova break Shostakov out of prison to learn Dreykov's location. He tells them to speak with Vostokoff, who lives on a farm outside Saint Petersburg, where she developed the chemical mind control process used on the Widows. There, Belova reveals that while they were not a real family, she believed they were so. Afterward, Vostokoff admits she sent their location to Dreykov. His agents arrive and take them to the Red Room, an aerial facility.
Vostokoff and Romanoff use face mask technology to switch places before being captured, allowing Vostokoff to free Shostakov and Belova from their restraints. Meanwhile, Romanoff confronts Dreykov, who sees through her disguise. Romanoff learns Taskmaster is Antonia, who suffered damage severe enough that Dreykov put a chip in her head. This made her the perfect soldier, capable of mimicking the actions of anyone she sees. Romanoff attempts to kill Dreykov but fails to harm him due to a pheromone lock installed in every Widow. Dreykov reveals that he controls Widows worldwide via his desk console. Romanoff intentionally breaks her nose, severing a nerve in her nasal passage to negate the pheromone, and then attacks Dreykov. Shostakov battles Taskmaster, while Vostokoff takes out one of the facility's engines and Belova searches for the other Widows, who have been sent to protect Dreykov. Together, Shostakov and Vostokoff lock Taskmaster in a cell.
Dreykov escapes as the Widows attack Romanoff, but Belova creates an antidote bomb that releases the Widows from mind control. Romanoff gets into the control desk and copies the locations of the other Widows worldwide as the facility begins to explode and fall. Romanoff retrieves the two surviving vials of the antidote and frees Taskmaster from the locked cell. Vostokoff and Shostakov escape via a plane just as Belova takes out Dreykov's helicopter, killing him. In freefall, Romanoff gives Belova a parachute before battling Taskmaster. After landing, Romanoff uses the antidote on Taskmaster, freeing her from servitude. The freed Widows arrive as Belova, Vostokoff, and Shostakov say goodbye to Romanoff. She gives Belova the last antidote vial and the portable drive, telling her to find and free the other, still mind-controlled, Widows. As they leave with Antonia, Romanoff awaits Ross and his men, who have arrived to apprehend her.
Two weeks later, Romanoff reunites with Mason, who supplies her with a Quinjet. She leaves, intending to free the imprisoned Avengers.
In a post-credits scene set after Romanoff's death, Belova encounters Contessa Valentina Allegra de Fontaine at Romanoff's grave. De Fontaine assigns Clint Barton, whom she claims is responsible for Romanoff's death, as Belova's next target.
