FBI agent Ivy Cross discovers her brother Leo is on a dark web death auction list. Each "item" is a person responsible for the Horizon Tower collapse five years ago—a disaster that killed 17 workers, yet only 16 bodies were ever claimed. The Auctioneer runs a live Bitcoin-bidding execution show, funneling every winning bid into a trust fund for the victims' families. As Ivy investigates, she uncovers that her superior McCallen took bribes to cover up the tragedy, and that her brother Leo is the Auctioneer's accomplice. The Auctioneer reveals himself as Daniel Wu—a survivor mistakenly pronounced dead, who spent five years orchestrating this reckoning. In the end, Ivy resigns from the FBI and opens a workers' legal aid center in South Side, transforming vengeance into a different kind of justice: ensuring every overlooked injury is finally seen.
