Shen Zheng, a brilliant emergency surgeon, dies from public defamation after a catastrophic medical incident in Mei City. In her past life, he tried to expose medical malpractice and cover-ups by corrupt hospital executives, yet her warnings were ignored. A deadly outbreak swept the city within 24 hours. Countless patients lost their lives, and he was framed as the culprit, dying in despair.
He reawakens, transported back exactly 24 hours before the disaster strikes. Now he has a second chance to rewrite fate. Standing in the emergency room of Mei City General Hospital, Shen Zheng carries full memories of every crisis, hidden infection source, and the lies her rivals plan to spread.
His former colleagues and scheming superiors dismiss her urgent warnings. They mock him for spreading baseless rumors and attempt to block her from accessing patients and medical records.
