Dramatic climate changes are sweeping the world, all food crops have been harvested, and famine has devoured human civilization. The "granary" has become the target of frenzied competition for all forces. Agricultural scientist {Gu He} grabbed the last batch of highly resistant seeds of hope and led the remaining scientific research team to hide in an abandoned underground farm. They cultivate seedlings in the dark, fight against hunger, radiation and mutant creatures, and also resist the crazy plundering of predators. Gu He must not only protect the seeds, the only hope of life, but also break through the suspicion and selfishness of the survivors and persuade everyone to work together to rebuild the agricultural ecology. On the barren ruins, the germination of a seed will eventually illuminate the glimmer of continuation of human civilization.
