The Black Widow returns to the Red Room
bearing Winter Soldier's cyborg arm and Hawkeye's broken bow to prove
she has killed them. She is promoted to Commander and put to training
young ballerinas in the ways of assassins. Meanwhile, Clint and Bucky
are trapped in the panic room of the building Natasha destroyed to
fake their deaths. After a lot of hard work they finally make their
way out to be met by firefighters. Clint reveals he has a tracking
device in his bow and they follow the signal to a secret house set up
by Natasha where they find Sally "Skids" Blevins (hidden since her apparent
death) and Ursa Major. When Bucky, Clint and the bear arrive at the
Red Room HQ, Natasha springs her trap and starts killing the Red Room
operatives. Clint and Bucky go through the building, the latter
shooting all of the guards while Clint tries his best not to be
beaten by a room full of ballerinas. They finally reach a room where
Black Widow is fighting a small army of clones of herself and she
tells the guys to help her kill them all, putting an end to the Red
Room program for replacing its agents. The last of the Red Room
forces arrive and fire upon the heroes; Natasha opens the door that
admits Ursa Major and the ballerinas and the enemy is wiped out.
Natasha takes clones of Yelena Belova and Anya/Orphan Maker and has
Epsilon Red give them all of their memories back and then she sets the
psychic free by killing him. The two guys carry the clones out; Black
Widow goes back inside to blow the place up, keeping the secrets out
of everyone's hands and vanishes....
As the firefighters try to bring the
mess under control, Sally tells the two guys they are idiots. A
fireman brings the guys letters he has found addressed to them.
Clint's is an apology from Natasha and a tearful farewell, asking him
not to follow her. Bucky's is a note asking him to meet with her if
he wants to join her for her next mission. The guys do not reveal the
contents to one another....
