One lazy morning an old man wanders into a witch's shop. The young witch Marjolaine greets him at the counter.
The old man produces a box which he claims to contain his heart, and asks for it to be delivered.
The store's owner, the wise Madame Odette, refuses to do business with the man, but a revelation leads the apprentice to accept the request, even if it is against her master's wishes.
With nothing but a picture to go on, The Witchling heads out into the city.
