My sister doesn't leave home

Luna can't get out of the house. Not even to buy a gift for her little sister.

After an unexpected trauma, Luna (25) is no longer able to leave the house.She is failing to be a good example for her 10-year-old sister, Aurora. The little sister reacted very differently by starting to dress every day like the great women she admires: Frida Kahlo, Coco Chanel, Emmy Noether. On Aurora's birthday, Luna discovers that her gift will not be delivered to her home and that she will have to pick it up directly at the delivery branch. How will Luna react?
