When a powerful earthquake hits Xichuan, lawyer Luo Ben rushes to the disaster zone to search for his mute younger sister, Luo Yuan. There, he meets the dedicated Light Chaser Rescue Team, led by the calm and capable Captain Qing Shan, and reconnects with Xiong Fei—his sister’s friend and a key member of the team. He also crosses paths with Dr. Zhan Yan, a woman he once underestimated but now comes to respect deeply.

Moved by the courage and unity of the rescue volunteers, Luo Ben decides to join the team. Alongside new recruits Zhou Min Ming and Ding Ding Ding, he undergoes rigorous training and faces life-threatening missions—battling earthquakes, fires, floods, and storms.

Through shared hardship and unwavering dedication, the team grows stronger together. And in the midst of danger, compassion, and sacrifice, unexpected love begins to blossom.
