Courier Chen Qiusheng encounters a sick elderly man who has lost his way on the street. He offers to take him to a hotel, then takes a day off the following morning to accompany him to the hospital and lends him money to cover the examination fees. The elderly man is diagnosed with early-stage stomach cancer and receives timely treatment. Meanwhile, Qiusheng's own difficulties are eased with the help of his coworkers and neighbors. This is a story about strangers supporting one another: you help me, I help someone else. The simplest acts of kindness in this world take root and blossom in the most unexpected places.
