What is left behind?
The dancer is returning to the Antarctic city where he grew up, and taking Lao Bai back to the zoo where the rhino was born.
But Antarctica is no longer the place he remembers. War and climate change have left cities in ruins and species disappearing one by one.
As they travel through what remains, the girl begins photographing what they find.
At first, the camera is simply a gift.
Gradually, it becomes something else.
A way to remember what may soon be gone.
