Seven years after her daughter Maya went missing, Sarah found her at a forest retreat, only to discover that her husband, Julian, had handed their daughter over to Dr. Claire—a psychologist—as an experimental subject to repay a supposed debt for saving his life. Sarah was placed under house arrest and falsely diagnosed with mental illness, but she managed to contact Agent Miller with the secret help of a doctor. The police eventually rescued Maya, and court proceedings exposed the years-long "debt of gratitude" ruse fabricated by Claire. Afterward, Sarah dedicated herself to studying psychology and founded a rehabilitation center, helping many traumatized children emerge from the darkness.
