Chen Ye quits his city job, sells his car and house, and returns to Qingshi Village, where he turns an abandoned grain depot into an agricultural machinery repair shop. Before the busy farming season, he works through the night to repair the village's farm machinery, only for Wang Dahai to confiscate the keys in the name of collective management. With no one who understands the technology, the machines begin breaking down one after another. Only then do the villagers understand the value of expertise and integrity and rediscover Chen Ye's original determination to protect his hometown. A test of responsibility and trust begins.
