Kane Blackwood is ambushed in a back alley and saved by a homeless girl named Ellie Walker. The string of old keys linked by paperclips at her waist becomes his only clue to find her. Ellie wanders the streets, fighting to keep custody of her younger sister. Kane is used to solving problems with money, but Ellie teaches him how to stand and live. Starting with a bowl of overcooked noodles, two people who learned to read danger through sound navigate courtrooms, black markets, and abandoned boxing rings—completing a redemption about standing rather than kneeling, proving that living doesn't require mortgaging one's dignity.
