In the war-torn Republic of China, the fates of underground party members Chi Yu and Gu Yuan were closely linked by the fetters of "the fish in the pond misses the old Yuan". Gu Yuan, a young girl from the Gu family who returned from studying abroad, used her family business as a cover to join the revolution; Chi Yu, a gentle and tenacious person, used her brush to record the undercurrent of the times and convey secret information. During the storm in Shanghai, they exchanged information late at night in the mansion, handed over materials behind closed doors in the warehouse, and forged a life-and-death friendship in troubled times.
Purpose: Personal love and feelings of family and country
