Ten years ago, Serena Sutton's father, deep in gambling debt, sold his daughter to human traffickers. Serena's mother, Bianca White, tried to chase but was stopped by Serena's father. She embraced Serena, putting a bracelet on her wrist, before being knocked unconscious by traffickers. Waking up, she saw Serena pulled onto a train. She watched helplessly as Serena was taken, vowing to find her.
