Rain over Shanghai

In 1943, the isolated city of Cangcheng. Top-secret Japanese military telegrams keep appearing, and Yan Qing, a Chinese Communist underground agent codenamed "Swift," is working undercover as a radio engineer. He must decipher the enemy's final plan while protecting Bai Zhi, a contact whose identity is shrouded in mystery. Amid layers of deception, every transmission is a life-or-death choice, and every sound of rain could be a final farewell. As trust and betrayal intertwine, they use their faith to light the darkness, staking their lives to protect the faint glimmer before dawn.
