Plot Summary

Cultural Revolution's Violent Turmoil

Brutal chaos during Cultural Revolution

In 1967, China is engulfed in the Cultural Revolution's madness. Ye Zhetai, a physics professor, is publicly humiliated and killed by Red Guards for his refusal to denounce scientific truths. His daughter, Ye Wenjie, witnesses the horror, which shapes her future. The chaos of the era is depicted through the violent struggle sessions and the ideological fervor that consumes the nation. Ye Wenjie, traumatized by her father's death and the betrayal of her sister, is sent to a labor camp in the Greater Khingan Mountains, where she finds solace in the natural world and the book "Silent Spring."

Silent Spring's Profound Impact

Environmental awakening through Silent Spring

Ye Wenjie, now in the labor camp, is deeply moved by Rachel Carson's "Silent Spring," which opens her eyes to the destructive impact of humanity on nature. This revelation leads her to question the moral fabric of human society and the potential for an external force to bring about moral awakening. Her thoughts are interrupted when she is falsely accused of counter-revolutionary activities, leading to her arrest. However, she is unexpectedly offered a chance to work at the mysterious Red Coast Base, a decision that will change her life forever.

Red Coast's Hidden Purpose
