Welcome to Darkenhall, an elite school for difficult teenagers. At first glance, this is an ordinary educational institution, but in fact, danger and darkness are hidden behind high walls... Abigail's life is divided into "before" and "after," as soon as she crosses the threshold of school. In a new place, the girl meets the Tremblay brothers, Tristan and Bastian, but makes a terrible mistake by stealing their ring. The girl does not yet understand what dark power she freed. After all, Tremblay is not an ordinary student, and the ring is not just a decoration. Now Abigail is in great danger, and she must remember: a kiss with Tremblay could cost her her life.
