At the local snow lodge’s Snowboard Meet, ace snowboarder Mia, trying to raise money for a new Heartlake City animal shelter, enters the fiercest race of all – the Boardercross. Then, while practicing, she has an accident and hurts her ankle. She insists it’s no big deal, but once she heals and tries to resume practice, the usually fearless Mia finds she’s now terrified of snowboarding! With the help of her Friends, she tries hard to overcome her fear, but her nightmarish visions of snowboard monsters and jeering snowmen have her shaking in her bed. She backs out of the race, disappointing her Friends and herself. Finally, when an avalanche traps Fiona, Mia is forced to overcome her fears and race to the rescue.
