A sudden viral disaster swept the world, and the end was coming. The cities of the past were reduced to ruins, and people's hearts were sinking into despair. Lin Mo, an ordinary courier, still uses humor and wisdom to laugh at himself to survive under the pressure of the apocalypse. Through encounters with Zhao Qing, Li Dayu, Xu Rui, Wang Min and others, several stubborn survivors with different personalities formed a small group, making jokes and encouraging each other, breaking the barriers between people during their escape and adventure. From despair at the end of the world to searching for glimmers of light, they use self-deprecation and humor to resolve crises, resolve conflicts within and outside the team, and gradually lead more survivors out of their spiritual haze and ignite hope in the darkness. They traveled through the crisis-ridden ruins, experienced betrayal, redemption, sacrifice and laughter together, and finally gathered a glimmer of light to rekindle humanity and bring hope of recovery to the disaster-stricken world.
