Lin Jianxia inherited an old photo studio that was on the verge of closing down.
She discovered that by repairing some damaged old photos, she could see one minute before and after the shutter was pressed.
Some people bring family photos and want to know why there is a stranger in the photo; some people cut out the teacher in the graduation photo, but beg her to put it back twenty years later; some people treasure an empty chair, saying that it is the most important place in the family.
Lin Jianxia searched for the truth for them, but also paid a price - every time she entered the photo, she might lose a piece of her memory.
Until she restored her own family portrait.
In the photo, she is young and holding the hand of a strange girl, calling her sister.
But the whole family said: You never had a sister.
