Ludmilla, a young student, is nearly struck down when her plane is hit by lightning, and she subsequently lands on the back of a flying dragon in New York. But is this really still New York? At first glance, it seems so, but upon closer inspection, quite a few things are different: not only are there no electricity or cars, but there are also plenty of mythical creatures. In the background of this bizarre parallel universe, the Preshauns hold the strings, seemingly cute but somewhat pedantic beings resembling squirrels, with a well-founded preference for tea. In this mirror world called Ekhö, Ludmilla must now find her way. Unfortunately, she has clung to her seat neighbor Juri on the plane, who now has to follow her every step. And even worse, she is occasionally haunted by the restless spirits of the recently deceased.
