Follows ten year-old Johnny who stands out in different aspects way beyond his age. Things change when his new teacher sees his potential, believes in him and wants to open a new world to him.

　演而優則導的瑪莉路易斯‧依莉貝以令人驚豔的光影戲法改編德國文學與音樂中的經典作品《魔王》。導演一方面結合自然場景、歌舞疊影與特技攝影，成功地詮釋歌德敘事詩中的奇幻想像；另方面也巧妙地運用蒙太奇式的剪輯手法，體現舒伯特藝術音樂中充滿動態感的創作調性。依莉貝以懸疑、獨特的視覺語彙成為開創法國有聲電影史新頁的代表人物之一。
