A self-described tomboy and former skateboard champion finds her footing as a chalet girl at a posh ski resort in the Alps, and enters into an unlikely romance while preparing to take part in a competition that will remind her how it feels to be a true champion. Kim Matthews is a 19-year-old (Felicity Jones) who thought her best days were far behind her. A fast-food worker who struggles through endless shifts to support herself and her father, she is completely stunned when she lands a catering job at a popular ski resort. Having never lived high on the hog, it's a world that seems as alien to her as life on Mars. But in time, the nimble skateboarder discovers the joys of snowboarding and decides to take a shot at a major competition staged to celebrate the end of the winter season. While trying to fit in and mastering the art of snowboarding, however, Kim starts to fall for her boss' son Jonny (Ed Westwick), a handsome young skier who seems to have taken a liking to her, yet still seems strangely elusive.
