Before a torrential storm hits, Chen Lan, captain of a rescue team, discovers that the cracks at Eagle Beak Cliff are shifting at an accelerating rate. She demands that Yunling Scenic Area immediately close its dangerous hiking trails, but manager Gao Shengyuan drives her away. To protect visitor numbers, Gao deletes warnings, falsifies inspection records, and sends unqualified personnel into the danger zone. Using monitoring data and on-site evidence, Chen Lan exposes the truth and evacuates every visitor before the landslide strikes. Ultimately, the scenic area's safety rating is suspended, and true rescue work begins with a simple order: "No one is allowed in."
