When a picture-perfect holiday first date ends in a frosty misunderstanding, Peyton and Ethan's spark is snuffed out before it can catch fire. Years later, fate - and a Christmas blizzard - intervene, reuniting them at their friends' surprise engagement retreat in the snowy mountains. Stranded together with the roads closed and the world outside blanketed in white, old feelings begin to thaw. As Christmas week unfolds, they'll have to decide whether to keep their hearts on ice... or finally melt into the magic that never quite went away.
