In a small place called Gatlin, the big boy Ethan Witt (Alden Ehrenreich) grew up here. Although he has been troubled by the same nightmare for a long time, Ethan never intends to leave here. He is used to the quiet and backwardness of the town, and is also used to the various supernatural legends and banned books that have been lingering here for hundreds of years. On this day, a beautiful girl broke the tranquility of Gatlin. Her name is Rena Dukai (Alice Englert), and she inherited a local villa that is rumored to be haunted. Ethan obviously likes Rena, who seems gentle and amiable, but the various abnormalities that follow make Ethan's classmates and even the locals regard the girl as a witch practicing evil magic. In any case, Ethan and Rena are still unstoppably attracted to each other. This is a taboo love between them that is unforgiven and hides countless amazing secrets...
