Plagued by nightmares and sleepless nights after a tragic loss, Park Ranger Samantha Takoda Tyler longs for a calm day at Grand Teton National Park in Wyoming. But when she's summoned to the chief ranger's office and introduced to Halie Walker, a photojournalist working for The Wild International, her day is anything but calm. When she's assigned to look after Halie, their meeting transforms into a quarrelsome exchange. Over time, the initial chill between the women warms. They grow closer as they spend time together and gain appreciation for each other's work.
But Sam's fear of loss coupled with rising jealousy over an old lover's interest in Halie grinds their budding relationship to a halt. Halie finds that anywhere near Sam is too painful a place to be, and Sam is unable to find the key to open the door to a past that she's purposely kept locked away.
With fires raging out West and in the Targhee National Forest, Sam works overtime, helping fill the staffing shortage. She misses Halie and wants to take a chance with her. Before she gets the opportunity to explain herself, Sam learns the helicopter Halie is on has crashed. Ahead of an oncoming storm, Sam races to the rescue. Can she save the woman she loves? Or will the past replay, closing Sam off from love forever?
