Julien, an aging
widower, collects butterflies. Isabelle and her eight-year-old
daughter Elsa have just moved into his apartment building.
The young mother is usually out, and lonely little Elsa
starts visiting Julien. One day, Julien decides to go to
the breathtaking Vercors plateau in search for a rare breed
of butterfly, the Isabelle. He thinks he is alone, but young
Elsa has managed to tag along on the trip. The little girl
asks tons of questions, upsetting the tranquility that the
old man longed for.
