Zhi Shi Lang is a turf replanting and compaction maintenance worker for channel slope protection. He is very skilled but always hides his thoughts in the vibration of the compactor. She feels guilty for her unintentional mistake during a rescue operation two years ago. She took the initiative to transfer and drifted away from her duty partner Zhou Yan. After returning to the central channel two years later, Zhou Yan is still her partner. If the turf is compacted too densely, it will die due to lack of oxygen. If the turf is not compacted, it will hang in the air and collapse. Every step of her operation is as precise as a ruler, but facing her old partner, the layer of soil in her heart cannot be flattened. Heavy rains washed away the grass roots and exposed them, and the growth varied with the seasons. When the slope protection faced danger again, she discovered that there was another layer of truth hidden behind the misunderstanding. The fate between people turns out to be like turf and slope. They need to fit perfectly to withstand the wind and rain together.
