Seventeen-year-old Valerie Russell runs away from her hometown to New York to start a new life there, and finds herself in the company of tramps living in the labyrinths of the city subway. However, it soon becomes clear that they are far from alone there. In the most secluded corners of countless tunnels hide fairies - fairy-tale creatures, the reality of which is difficult for modern people to believe.

Acquaintance with a terrible and at the same time unusually noble troll named Ravus confronts Valerie with a difficult choice.
