Every winter, three families gather in an old house in the country to celebrate the New Year. This year, 15-year-old Leah and the other two teens discover that the house has a dark past: a deathbed confession led the police to the buried body of a teenage girl earlier in the year, who had gone missing 50 years before.

As the teens investigate the morbid history, terrible things start happening around the house.

And if Leah isn't careful, this New Year might be her last.
