The two-way redemption story of Gu Yunshu and Toya spans decades. Gu Yunshu became an orphan during the famine in the south. He was adopted by the Batu family, a grassland herdsman, and grew up with his adopted daughter Toya. A sandstorm claimed the lives of her adoptive parents, and they were accidentally separated. Toya was abducted and trafficked, and her pseudonym Lin Xidi suffered from domestic violence for a long time. Many years later, Gu Yunshu, now a lawyer, reunited with the broken Toya, and helped her escape from the sea of misery without fear of resistance, and pursued the case of human traffickers and perpetrators. The two returned to the grassland, went to Tiananmen Square and watched the sea to fulfill their youthful promise. Toya, who was seriously ill, saw the dawn of cure. In the end, Toya stayed in her hometown to teach, and the two took root in the grassland.
