A sudden disaster swept the world, social order collapsed, and the end of the world came. Courier boy Lin Hao and a group of ordinary people with different personalities struggle to survive in the afterglow of the apocalypse. In a desperate situation, the survivors not only face the threats of hunger, disease and mutated monsters, but also need to overcome the desolation of the human heart. Relying on his humor and extraordinary wit, Lin Hao united with various "cheap friends" to form the "Apocalyptic Laughter" team. While exposing each other's scars and warming each other up, they use wisdom to solve difficulties, and use ridicule to dilute fear, and work together to find traces of their families and the warmth of humanity. After experiencing betrayal, loss and new hope, the team finally rebuilds the bond of trust, explores the recovery and future path of human civilization, and welcomes the dawn of new life in the flames of war that have not yet been completely extinguished.
