On the day of his retirement, Nevada homicide detective, Jerry Black, is shaken by the murder of an 8 year-old girl in the mountains. The grieving mother begs Jerry for answers and Jerry swears on his soul to find the killer. When an ambitious young cop wrenches a dubious confession from a simple-minded suspect, Jerry won't let the case be closed, at least not for himself.
Driven by his promise, the tenacious retiree buys a rundown gas station at a strategic intersection in the mountains near where the crimes occured and begins his investigation. He befriends a single mother and her young daughter but neglects to tell them what his true motives are for relocating to the mountains. Will his oversight prove fatal, or will he catch the real killer in time?
