Once in a Full Moon: In this whimsical and sensual world, the Moon and a Little Vampire share a love story as intoxicating as it is impossible. The Moon petrifies with sorrow at the vast distance separating her from her beloved. The Little Vampire is then faced with a fateful choice : renounce his immortal soul to join his lover for one single night. He embarks on a journey strewn with tantalizing (or thorny) temptations and mischievous spells, all conspiring to lead him astray from his quest.
