Siblings Jen and Dante are social media influencers and post videos of themselves doing extreme sports. But when they jump out of a helicopter to ski down a mountain, the stunt goes awry. Dante's ankle gets slashed, and the helicopter crew -- who were supposed to be waiting at the bottom of the mountain -- are nowhere to be found. As the confused teens seek answers, they meet up with some locals and soon find themselves flesh to fang with a group of frost vampires! Their only hope for survival is to make it to sunrise, when the vampires become dormant under the snow once again.
