Felicity Jones delivers an impressive performance as Kim Mathews, a nineteen-year-old skateboarding talent whose life is shattered by the tragic loss of her mother in a horrific car accident. As she learns to cope with this new reality alongside her father (played by Bill Nighy), Kim seeks comfort in the monotonous days spent working at a fast-food burger joint to keep the household afloat. However, as financial pressures mount, her search for a better job leads her to an unexpected opportunity.
When her friend suggests she try her hand as a "chalet girl" in the stunning Alps, Kim initially views it as a mere dream. With a stroke of luck, she secures the position at the last moment, stepping into the role of the injured chalet girl. In her new environment, Kim initially clashes with [Georgie](https://Tamsin Egerton), her fellow chalet girl, as their backgrounds couldn't be more different—Kim is a city girl inexperienced in snow sports, while Georgie epitomizes the upscale Alpine niche.
Amidst this dynamic, Kim becomes attracted to Jonny (played by Ed Westwick), the affluent son of Richard (Bill Nighy) and Caroline (Brooke Shields), who is already entangled in a relationship with Chloe (Sophia Bush). Undeterred by this complication, Kim is determined to conquer snowboarding and finds a mentor in Mikki (Ken Duken), who encourages her to enter a €25,000 snowboarding competition.
As Kim's skills progress, so does her unexpected friendship with Georgie, allowing them to move beyond their initial tension. Meanwhile, Kim’s relentless pursuit of success in snowboarding becomes a crucial way for her to face the emotional scars stemming from her mother’s tragic fate.
A twist unfolds as Jonny lingers at the chalet after a business trip, expressing an unexpected desire to learn how to snowboard from Kim. Their day together culminates in a moment filled with unspoken chemistry, however, the next morning brings a shocking revelation from Caroline, who reveals that Jonny is engaged to Chloe. Dealing with a whirlwind of emotions, Kim decides to leave but is persuaded by her father to remain for the competition, as it is what her mother would have wanted.
In a bid to reshape his future, Jonny makes the tough choice to end his engagement at the party, admitting to the truth of his feelings for Kim. However, news of this breakup leaves Kim indifferent to his advances. Supported by Mikki, Kim competes fiercely against elite snowboarders but is haunted by memories of her mother, ultimately finishing in a respectable 21st place. Yet, fate intervenes when world champion Tara Dakides (playing herself) withdraws, offering Kim a surprise chance to take her place in the competition.
With a renewed sense of purpose and a vision of her mother's encouragement from the sidelines, Kim delivers a stunning high-jump performance that leads her to victory. As Jonny reconciles his past relationship, he reappears to offer a sincere apology. Their connection reignites during a playful exchange, culminating in a tender reunion that is witnessed by Richard and Caroline, who, for the first time, support Jonny's budding romance with Kim.
