Sometime in the future, Rio de Janeiro lies in ruins—its society fractured by class warfare, its people consumed by a brutal spectacle known as the Beast Race. In this high-stakes competition, masked runners tear through a devastated city while the elite wager on their lives. Every runner must pledge a collateral: a human life condemned to the mysterious, dreaded Coast of Hell if they lose. Mano leads the Death Perimeter, a rebel zone devoted to dismantling the race. But when he discovers his younger sister has been offered as collateral by her boyfriend, Mano is forced to do the unthinkable: enter the race he’s spent his life resisting.
