In order to complete his imaging assignment in the summer, an American international student broke into the life of Xu Mandong, a retired professor on Yuyuan Road, Shanghai. She breaks the rigid rules of care and uses dancing, delicious food, and late-night drives to help the elderly in wheelchairs smile again. The two of them explored the centuries-old history of the streets under the sycamore tree, while Xia Tian secretly used AI technology to restore the grand scene of Yuyuan in the old man's memory. Xia Xia was fired and returned to China for being "unprofessional", but her graduation work helped the elderly relive the old days and the voices of their loved ones. With the arrival of spring, Xu Mandong, who stood up again, smiled at each other with the returning summer, and the dead tree became spring again. This encounter produced healing flowers on Yuyuan Road.
