At the moment when the New Year's Eve fireworks burst into bloom, a zombie virus swept through Cangnan City, turning half of the human race into bloodthirsty monsters. Su Yao, who had just escaped from death among the corpses, was abandoned by her relatives in an abandoned town. She struggled to survive in the apocalypse with only a half bottle of mineral water and a broken backpack. She is an inexperienced survival novice, hiding from zombies and looking for supplies. Every step she takes is like walking on thin ice, struggling to move forward in fear and despair. Until late one night, she dreamed that mysterious light points were guiding the underground laboratory deep in the city, where the secret of the origin of the virus was hidden, and it was also related to the hope of human survival. In order to survive and find the truth, Su Yao mustered up the courage to embark on the dangerous journey to the main city. Along the way, she encounters zombie sieges and tests of human nature, but unexpectedly meets like-minded partners - a calm scientific researcher, a tough veteran, and a clever young survivor. They fought side by side, broke through numerous crises, and gradually uncovered the man-made conspiracy behind the virus. From an abandoned orphan girl to a warrior leading hope, Su Yao, guided by dreams, counterattacked and grew up in the apocalyptic ruins, using courage and trust to fight against the darkness, guarding the glimmer of light in rebuilding her homeland.
