Nine-year-old Sophia daydreams about the beautiful Princess Polly and the fairytale land of Polldovia. One day she finds herself inhabiting this fantasy world but a very different one to that she has so far imagined. She and Polly are in Suspyria, Polldovia's war-ravaged neighbour, ruled by the warlord Naberius and his monstrous Dark Army. Imprisoned in Naberius' fearful dungeon, escape is their only means of survival and a hair-raising chase ensues.
