Corporate lawyer Ava Burch has had enough of the big city and moves to the small town of Cuervo. When she and her dog, Huck, discover an abandoned campsite on a volunteer search-and-rescue mission, she's perplexed, but she carefully photographs it all the same. All Deputy Sheriff Grant Wycoff can see when he looks at Ava is a city slicker. But when she tells him of her discovery on the trail, he sees there's more to her than meets the eye. With time running out, Ava and Grant must work against the brutal heat from both the Texas sun and their own electric chemistry to solve the case.
