An underappreciated live-in son-in-law refuses to accept his fate and blazes a new trail through farming and livestock breeding on barren hillsides. In the 1980s, Wu Dashuan endures relentless humiliation from the Wang family. After being driven out of their home, he uses the mountain farming and forestry techniques taught to him by a deceased agricultural professor to lease barren mountains and start his own business. Overcoming malicious suppression and fabricated rumors spread by Zhao Sihai and others, he takes the lead in establishing an agricultural and forestry cooperative, guiding the villagers toward shared prosperity. Meanwhile, he uncovers the secrets of his own origins, calmly confronts family feuds, and remains true to himself as he builds a reputable local agricultural and forestry brand through outstanding quality.
