Twenty miles across the North Dakota border, where the scenery goes from rolling grass prairie to pipeline fields, detective Cassie Dewell has been assigned as the new deputy sheriff of Grimstad - a place people used to be from, but were never headed to. Grimstad is now the oil capital of North Dakota. With oil comes money, with money comes drugs, and with drugs come the dirtiest criminals hustling to corner the market.

In the small town resides twelve-year-old Kyle Westergaard. Even though Kyle has been written off as the ‘slow’ kid, he has dreams deeper than anyone can imagine. He wants to get out of town, take care of his mother, and give them a better life. While delivering newspapers, he witnesses a car accident and takes a mysterious bundle from the scene. Now in possession of a lot of money and packets of white powder, Kyle wonders if his luck has changed.

When the temperature drops to 30 below and a gang war heats up, Cassie realises that she may be in over her head. As she is propelled on a collision course with a murderous enemy, she finds that the key to it all might come in the most unlikely form: an undersized boy on a bike who keeps showing up where he doesn’t belong. Because a boy like Kyle is invisible. But he sees everything.
