After Ivan's death, Natasha was recruited by the KGB and trained in the covert Red Room facility, where she was enhanced and became the elite assassin known as the Black Widow. Meanwhile, Clint Barton, who lost his parents in a car accident, honed his archery skills under The Swordsman's mentorship but later turned against him due to his criminal activities.

After a fierce confrontation, Clint convinces Natasha to defect and join S.H.I.E.L.D. Together, they plan to take down the Red Room, leading to a showdown with Natasha's successor, Yelena Belova. Despite initial hostilities, Natasha subdues Yelena and teams up with Clint to destroy the Red Room. They defeat the Headmistress and escape, only to be taken into custody by S.H.I.E.L.D.
