Three college freshmen go missing from their rural hometown of Kelly's Falls while on Christmas break. Their cell phones, coats, and purses are left behind, but the girls have disappeared without a trace. As the days turn into weeks and the investigation grows cold, twenty-three year old Buffalo police officer Shea O'Connor is called on to dig up leads undercover. But whoever was behind the girls' disappearance was only warming up, and they have set their crosshairs directly on her.
