Laura and her friends find themselves faced with even greater stakes (no pun intended) at Silas University after the mystery of the missing girls is solved. Having saved her roommate and a significant portion of the student body, Laura pretty much figures good has triumphed, until Silas erupts into total chaos. Come hell or Hogwarts, Laura and her friends are determined to unite the warring factions of the University, reinstate classes and traditions, and turn Silas into the welcoming bastion of inclusion and knowledge it was always meant to be. At least that's the plan! But nothing ever goes as planned - the past and future are about to collide in unimaginable ways, and relationships and friendships will be put to the ultimate test. If love has its sacrifices, just how far will they go?

Following the dramatic events of the Season II finale, Laura and Carmilla are stuck in the basement of the ominous Library of Silas University. Of course, the only logical thing to do is to have a Hollstein movie night.
