He Zhen, a martial arts school coach, suffers severe injuries in a construction site collapse while saving his brother-in-law, who owes gambling debts. While he is unconscious, his father-in-law takes advantage of the situation to swindle him out of 500,000 yuan in work injury compensation. His wife sides with her birth family, and a paternity test confirms that his son is not biologically his. Armed with evidence, he overturns the coerced agreement and freezes the Fan family's assets. His brother-in-law is sentenced to prison for illegal fundraising, and the old family home is auctioned off. After being discharged, He Zhen obtains a patent for agricultural machinery designs he drew in his hospital bed. Using crutches, he starts a business and wins a major provincial contract, rising from a disabled man to a successful business owner. In the end, he throws away his crutches, walks across the rooftop, and drives toward a new life.
