When a free-spirited wildlife photographer loses her Scottish terrier in a herd of bison, she sets out to rescue her furbaby before he is devoured. But will she succeed when Yellowstone National Park is chock full of boiling, bubbling, and rampaging hazards (both mammalian and geographical) — not to mention a rule-obsessed park ranger whose many rescues thwart her efforts to find her poor pup?

They say opposites attract, and when it comes to Kayla Dineen and Ranger Alexander Brandt, no two people have ever been more opposed…or attractive. Old Faithful isn’t the only thing making noise at Yellowstone this season.
