The Black Widow has been an Avenger and even an agent of S.H.I.E.L.D. But on her own time she searches for atonement for her past as a KGB assassin - in ways of which those teams just wouldn't approve. She goes undercover in Russia, but from its cold streets, the Hand of God reaches out to crush her - and it is as merciless as its name implies. Outmatched by the brute force of a powerful new villain, Natasha faces her deadliest test and discovers a deadly plot unfolding that spans the entire globe.
