The young and pretty witch Melusine does not understand why she does not find the great love. Nothing to do with her character, of course! The explanation is undoubtedly much simpler: she lives in a lost and sinister hole that the beautiful knights avoid like the plague. So she decides to give a little boost by throwing herself a spell. Horror! She is mistaken in her dosage and it is the whole world that adores her, admires her and wants to spend her life with her. It will take courage, ingenuity and humor to the clumsy to put things in order.
