Special Agent Dagny Gray is a member of a small FBI team with unprecedented independence. To maintain their autonomy, the team must continue to solve big cases. To stay on the team, Dagny must keep her personal demons under control. When Father Diego Vega tells her that undocumented workers are vanishing from a small town gripped by immigration politics, Dagny thinks she's found her next case. But without bodies or proof of foul play, her boss won't let her take it. Defying his orders, Dagny risks her career to investigate with Father Vega. The families of the victims don't trust her. The local police won't help her, and the sheriff wants to stop her.

Deep down, she worries that she's not going to find the missing men alive. But what she uncovers is more horrifying than anything she could have imagined.
