A sudden global "green tide" catastrophe caused all plants to undergo irreversible mutations in a very short period of time, becoming highly toxic or inedible, and even actively attacking humans. The ecosystem collapsed completely, and humans fell into an unprecedented famine. Su He, a once marginalized plant genetic scientist, survived the disaster. She has no golden fingers, only a vast amount of knowledge about botany and genetics in her mind and a tenacious belief in life. While other survivors were still struggling for a bite of food, Su He had already begun her "creation" plan in an abandoned botanical garden surrounded by mutant plants. Using the remaining equipment from the old world and her own professional knowledge, she risked her life to extract genes from poisonous weeds and try to cultivate a "seed of hope" that could adapt to the new environment and be edible for humans. However, the hungry survivors, the predators who covet her achievements, and the constantly evolving mutant plants have all become huge obstacles on her way to rebuilding her green home. Su He must race against time, use her wisdom and sweat to re-sow the hope of life in this dead land, and build a "Garden of Eden" that can feed all mankind!
