When Bea moves back to the country house where she was born, she finds her brother and sister still living in abject poverty. She will discover that her two siblings share the same ambiguous inclinations and more than one secret.

The short's main characters are Simone - a young and ambition-less unemployed man, and the titular Djinn - an ancient and powerful genie that is reduced to grant wishes in a small suburban office. The first of the two wishes for a job, whereas the second only wishes to steal as many wishes as possible to his "customer", to obtain as many years of life for himself. Both characters are running from a crisis: Simone from the economic depression, and the Djinn from a crisis of the imagination that is perhaps a direct consequence of the first.
