Emergency doctor Pei Qing once trustingly believed students' false reports about an epidemic, leading to the spread of the virus and her own miserable death. Reborn back to the reception moment, facing the four provoking internet celebrity college students once again, she decisively initiated a level-one risk control plan, locking down the hospital and enforcing mandatory quarantine. Despite facing pressure from family members and attacks from online public opinion, Pei Qing held firm to the bottom line of epidemic prevention, ultimately cutting off the transmission chain, bringing the involved parties to legal justice, and defending public safety and the dignity of a healer.
