During a covert mission to dismantle a notorious black market auction dealing in human trafficking, the Avengers uncover a darker truth—Hydra is branding and selling enhanced young adult girls. When Bucky Barnes spots a silent girl on stage with the Hydra insignia scorched into her neck, everything changes. Haunted by his own past, he defies orders and buys her to get her out before chaos breaks loose.

With the mission complete and the auction destroyed, Bucky brings the mysterious girl back to the Avengers Tower. Traumatized and wary, she doesn’t speak—but the mark on her neck speaks volumes. As the team begins to uncover her history, one question remains: was she just a victim, or something Hydra wanted to keep hidden?
