The world has been frozen for three years, and Jiangcheng has been reduced to frozen ruins. Former biological researcher Mu Mo was framed by his ex-girlfriend Su Qing as the culprit in the apocalypse, and he was left alone in a desperate situation. By chance, he rescued Lin Wan, the sister of his friend Lin Chen, who was besieged by looters in an abandoned parking lot. She was the only close relative who believed in his innocence in the past.
With this "trouble", Mu Mo took Lin Wan to hiding places such as laboratories, abandoned warehouses, and office buildings while avoiding the pursuit of the search team and Su Qing's forces. The frozen ruins are surrounded by dangers, and the two support each other amidst suspicion and dependence. Mu Mo escapes death many times with his ruthless skills, while Lin Wan gradually grows up in fear.
And Su Qing laid a dragnet, not only coveting Lin Wan, but also trying to eradicate Mu Mo. As the escape deepens, the truth about the virus leak and the suspicion of Lin Chen's death gradually surface. Mu Mo not only wants to protect Lin Wan, but also clears his grievances, recovers the blood debt from the betrayer, and fights a way out in the frozen apocalypse.
