The global environment has changed suddenly, and the apocalypse has come to the ruins of cities. Five ordinary people formed a team by coincidence, helping each other to save themselves in disorder and chaos, and breaking the oppressive predicament with wisdom, unity and humor. From searching for food and survival challenges to facing moral torture, mutual harm between people, and team rifts, they use jokes and absurd methods to resolve conflicts and find hope in despair. In the middle and later stages, a mysterious wanderer wakes up and joins, inspiring the team's concept of "laughing at the doomsday". They travel through the wasteland, fight against mutations and the collapse of human nature, and undergo suffering, transformation and mutual redemption. Finally, on the eve of the establishment of a new order in the apocalypse, they used their wisdom and smiles to lead more survivors to re-examine their lives and usher in the dawn of recovery.
