It's time for the annual winter camp at Anjeon University. A full weekend, deep in the mountains, with no parental supervision. But this is no ordinary getaway. It is 1980s South Korea, where police are always watching and even the slightest bit of self-expression can lead to arrest. Luckily, it's the only night of the year when generations of Korean had no curfew, no obligations, and no rules: Christmas Eve.

In the snowy mountains, everyone has a different plan for their one night of freedom. Hyun Sook is trying to restart her banned book club but has to hide from a boy she suspects of being a spy. Taehee and Kiwoo are trying to build up the nerve to confess their feelings for one another, while Suji pines after her crush, ready to risk it all and finally tell someone the secret she's been hiding for her entire life.

Acclaimed creators Kim Hyun Sook and Ryan Estrada deliver a cinematic, hilarious, and heartfelt story about the universality of growing up, making friends, and falling in love.
