Gabriel McBride is a 45-year-old detective working on a case of children aged around 5 or 8 who regularly go missing.

The case has been unsolved for a long time because the people trying to solve the case have often been thwarted or murdered.

From time to time, Gabriel received anonymous tips regarding these disappearances, but the anonymous person always asked him to be extremely careful.

And then one day, the hints and clues came together to form approximate coordinates... And the man headed there.
