Olivia "Liv" Durham has been trying to outrun her past ever since former Black Widows, Natasha Romanoff and Yelena Belova, destroyed the place that made Liv what she is. Like Natasha, she has been trying to erase the red from her ledger by doing good. As part of this effort, she joined the CIA's special ops team, the Thunderbolts. While there, she meets Bucky Barnes, one of the most annoying people on the planet. He doesn't take anything seriously, he always has some childish comment and he is way too laidback for his own good. Liv and Bucky are forced to go on a mission together to investigate some claims that former Red Room leaders may be trying to restart the Black Widows. Liv and Bucky need to gather some information to determine if this is true. However, they need to go in as a married couple to hide their true intentions. While on the mission, something is sparked between Bucky and Liv. Will Liv's past make the spark fizzle out before it has a chance to burn? Or will Liv and Bucky succeed in destroying the Red Room for good?
