Girls from immigrant communities have been disappearing for months in the Colorado town of Blackwater Falls, but the local sheriff is slow to act and the fates of the missing girls largely ignored. At last, the calls for justice become too loud to ignore when the body of a star student and refugee - the Syrian teenager Razan Elkader - is positioned deliberately in a mosque. Detective Inaya Rahman and Lieutenant Waqas Seif of the Denver Police are recruited to solve Razan's murder, and quickly uncover a link to other missing and murdered girls. But as Inaya gets closer to the truth, Seif finds ways to obstruct the investigation.
