Yale University. The start of a new year. Eighteen girls start the new year at the prestigious Yale University. New friendships, forbidden romances, and blazing conflicts arise within the girls, but it's nothing out of the ordinary. Until one night when the 18 girls discover an ancient, sinister secret festering underneath the schools grounds, their lives are irrevocably changed... forever. Will all 18 make it out alive, Or will their numbers dwindle until only one remains. Or none at all.
