After someone leaks the contents of the Sokovian Accords *cough* Vision *cough*, the world realizes the problem in restricting heroes' capability of saving the world. While they do acknowledge that heroes need to be held responsible, people think being saved outweighs the risk. So when they get word that there's a Hydra base they missed in Hungary, the Hungarian government has no problem with them coming and taking it out. But neither group expected it to be occupied by only two people. Steve recognizes Bucky, but not the woman he's guarding. Who is this woman, and why is she being guarded by Bucky?
