Archeologist Lindsey Attwood is distraught that her ex-husband has taken their eight-year-old daughter to Mexico for the summer. To take her mind off her worries, she agrees to visit her twin sister Laura and best friend Collie to help find stolen fossilized dinosaur tracks. Posing as a client for the horse psychology camp on the farm where the tracks were stolen, Lindsey discovers more than she bargained for, including a friendly mutt and hunky cowboy/veterinarian Zack Truitt.
