One early morning at a construction site, an older worker named Zhou is eating a steamed bun when Du Haifeng, a site manager, publicly humiliates him and kicks over his food. Unwilling to let his fellow workers endure such mistreatment indefinitely, team leader Han Zhenshan resolutely leads more than twenty workers away from their former employer to establish an independent construction repair crew. With jobs scarce in the early days of their venture, Han remains committed to professional integrity and refuses contracts that require cutting corners. He documents every detail and makes responsibilities clear. After facing accountability for an accident at their former site and safety challenges on new projects, the small crew gradually establishes itself through hard work and unwavering principles, earning market recognition and the respect that workers deserve.
