Twelve years ago, four children suddenly disappeared without trace. Now during the winter solstice, three of them returned out of nowhere as teenagers with no memory of what happened to them. Astrid, Tom and Sonja have to unite to face the prejudice of the villagers and to find out, what happened to them and where the fourth missing child is--Astrid's brother Max. Twelve nights after the winter solstice is the most dangerous time of the year as the border between human world and underworld is thin. And the kids--now adults--will discover that the ghosts from their nightmares are real and waiting for them.
