Veterinary assistant Mandy Woods sets out in southern Arizona to discover who is killing Mexican Gray Wolves, an endangered species. Her search for the killer with another Save the Wolves member named Charley, leads the two of them into danger that could be deadly for both of them.

As soon as Mandy begins to trust Charley, she learns of a secret he has kept from her—a secret that destroys her trust. Mandy knows the only chance she has of happiness is to face her fears and forge ahead alone with her dream to open an animal shelter for injured large animals. Even if this means denying her feelings for Charley.
