Premise
Black Widow reluctantly teams up with her old rival Silver Sable in stopping Viper from attempting to recreate Ulik's goal of unleashing the Midgard Serpent using Asgardian artifacts she stole from Amora the Enchantress. Meanwhile, the Avengers work to stop a turf war between Kree forces commanded by Yon-Rogg and Hydra units commanded by Silvermane over the same artifact under Viper's possession. At the same time, Iron Man and Wasp look after Riri Williams, a young girl with an superhuman intellect who developed her own prototype of the Iron Man suit through the nanotech resources she retrieved from Spencer Smythe, and Katrina, a young girl with the same technology and skills as Black Widow who is looking for answers about her past and the identity of her long lost mother, who seems to have a deep connection to one of the Avengers...

Plot
12 years ago, Natasha Romanoff had tricked the other Black Widows of the Red Room program into eliminating each other until the Red Room facility was destroyed once one of the graduated agents was near to learn that Romanoff violated their primary rule: never give birth to a half-breed child; Natasha had wooed an American agent of S.H.I.E.L.D. and given birth to a child girl named Katrina. Fearful that the Red Room headmasters may one day learn of her daughter's existance, Natasha decided to leave Katrina on the care of X-Man Colossus until the day she was ready. In present day, Black Widow is resuming her role as an Avenger and teacher in Avengers Academy, though she still regrets having not seen Katrina for years because of her role in the Red Room. Just then, during a fight against invading Hydra agents, she is aided and (soon after the Hydra agents retreat) taken to a fight by her old rival in the Red Room: Silver Sablinova / Silver Sable.

Having learned that Natasha was responsible for the incident in the Red Room facility, Sable had returned to get her revenge on Natasha (who only acknowledges that Sable is unaware of Katrina's existance) for inadventently causing her graduation to never happen. Their fight is cut short by Captain America and Spider-Man, who have been both focus on Hydra's next plot, which Sable was hired to intercept.
