Under the blazing sun, the urban village begins distributing disaster relief compensation. However, Lin Han's family is the only one left out because they live in the mountains, outside the disaster zone. Suddenly, he becomes the subject of gossip among the neighbors, but the experience only strengthens his resolve: rather than waiting for help and relying on others, he will depend on himself. He mortgages his homestead and takes his family up the mountain, personally carving out a cave dwelling on a sunny hillside. The villagers initially cannot understand his decision, but he remembers the wisdom passed down by the older generations. Lin Han holds no grudge against those who once looked down on him. Instead, he opens his doors and shares his knowledge with the neighbors, leading everyone in improving their cave dwellings and installing electricity. Gradually, the once-barren mountain becomes a thriving place full of life.
