Finlay and his family live in a village on the edge of an enchanted kingdom. His subjects are gradually being overcome by a disease for which there is no cure... Almost. Finley has invented a way to save her father. To do this, she needs to collect an everlasting leaf at night, which grows only in the Forbidden Forest. Only this plant can slow down the curse. The girl has learnt how to make coffins from it, but to collect even a little everlasting, she has to break the law. The citizens of the kingdom are strictly forbidden to visit the place, to cast magic and turn into animals, as they used to. And all because of an agreement between the late king and a demon. Finlay dared to break the ban and became a prisoner in the Beast\'s castle. Who is he and what drives him? The girl can try to save him and the whole forgotten kingdom, whose rulers have fallen into debauchery, by taming the monster in the Beast. But will Finlay be able to resist a powerful passion? And what will she choose when it comes to deciding which side to stand on?
