After his father passes away from illness, his older brother, Lu Lanxiang, inherits their father's construction company and most of the family fortune, while Lu Chuan receives nothing but a nearly scrapped Caterpillar 320 excavator and sets out to make a living on his own. Drawing on the solid geological knowledge and outstanding excavator skills he acquired during his military service, he starts with difficult construction projects that nobody else is willing to take on. Through extraordinary techniques such as layered rock breaking and precision leveling on sheer cliffs, he repeatedly accomplishes seemingly impossible feats and earns the trust and recognition of numerous clients. Meanwhile, his older brother makes one mistake after another because of his eagerness for quick success, eventually falling into serious trouble. Putting the past behind him, Lu Chuan reaches out to help his brother, who finally comes to his senses and starts over as an apprentice, working hard from the ground up. In the end, the brothers reconcile, and Lu Chuan grows into a well-known local entrepreneur in the earthworks industry.
