"Autumn Cicada" is set against the backdrop of the fall of Hong Kong in 1941. Ye Chong, a Communist Party member played by Ren Jialun, uses the codename "Autumn Cicada" to lurk among the top brass of the Japanese army. During the dangerous spy battle, he and Li Man and other comrades experienced misunderstandings, life and death, battles of wits and courage, and repeated crises. After his identity was exposed, he made a desperate breakthrough and returned to the battlefield, ultimately helping to win the Anti-Japanese War and writing a legend of passionate faith and youthful redemption!
