Plot
Black Widow is now the worlds most wanted assassin, fleeing the people she helped protect, Natasha has no choice but to continue her mission of bringing down the Great Wheel of the Zodiac which takes her to the one place she swore never to go...home.

Natasha seeks the help of The Headmistress who, in return for a favour, would grant her all the help she needs, including the help of Natasha's old friend turned rival, Yelena Belova, the second Black Widow. As well as The Winter Soldier who the red room had discovered unconscious in the snowy mountains, the Headmistress had the chip removed, but his memories had not restored, so now he did the will of the Red Room.

With the help of Yelena and Barnes, they went looking to recruit the heroes that would help them bring down Orion and Magadan and their organization "The Leviathan", starting with Ivan Vanko who had changed his ways and taken up the mantle of Crimson Dynamo in order to do good, Laynia Petrovna AKA Darkstar, The Drunken Man-Bear, Mikhail Ursus AKA Ursa Major and the Slavic God of the Storm Perun.

To Natasha's surprise, Yelena said they had one last stop, meeting someone she never thought she'd see again. The man she loved until he seemingly died in a plane crash, Alexei Shostakov, The Red Guardian. Natasha was stunned and betrayed, she talked to no one except Bucky who despite Natasha's efforts, remembered nothing of Steve or his history.

Natasha gradually put her feelings of betrayal aside in order to plan the attack on the leviathan base, Alexei and the Winter Guard would cause a distraction at the entrance while Natasha, Bucky and Yelena would infiltrate it and take down Orion and Magadan. When they infiltrated they found only the brute Magadan, Orion had known they were coming and had fled.

The three of them working together were able to bring the brute down, when Natasha went to chain him, Yelena stopped her and gave her a gun, telling her to become the person she once was, Natasha refused so Yelena spat in her face and killed him herself, calling her weak. The Leviathan had wanted to bring down the Red Room for years, The Headmistress had used Natasha like a pawn.

Yelena turned her back on Natasha and left to track down Orion who was planning on making a transaction of 10 million USD in Paris, now Natasha, Bucky and the eager to redeem himself Alexei, must go to Paris and capture Orion, before the Scarlet Widow reaches him first. Natasha must find a way to stop her old friend and prove to Yelena that she is stronger than she is.

In a mid credits scene, Natasha drops the Helmet of Orion in front of the Headmistress who looks up at her with a smirk "You didnt kill him..." she sighs "Well call you". In a post credits scene, a Man in a suit is reading a newspaper on the Iron Man.
