Former Army Ranger Chance Grayson takes chances like his name. He's the wild child of the Grayson brothers. After his 4th tour to Afghanistan and Iraq, he left the military and returned home to Hellfire, TX. An adrenaline junky he's afraid to slow down, afraid the memories of war will catch up. He rides a motorcycle and lives at the ranch when not at the fire station.

Army dog handler, Kate Bradley, left the military and adopted her military war dog. She hired onto the sheriff's department on the condition the dog came with her. New in town, she moves into a garage apartment and goes to work retraining her bomb-sniffing dog to find drugs.

Chance teams with Kate to find a local arsonist bent on blowing up Hellfire. They work close together to determine if their bogey is just burning buildings or creating a distraction in order to find something else. Meanwhile, the firefighter and the deputy spark a tinder of desire that threatens to go up in flames.
