Lin Yuan, a key technical specialist, is fired by his company through WeChat while on a business trip. With a major 2.8-billion-yuan project about to be signed, he immediately cancels his ticket and heads back. Dingchuan Company tries to erase his contributions and even forges his signature and fingerprints to make Lin Yuan the scapegoat for a project accident. At the signing ceremony with Guoheng Group, layers of hidden corruption are exposed one after another, revealing collusion among company executives and a scheme to drain the company of its assets. Armed with evidence, Lin Yuan joins forces with righteous colleagues and lawyers to fight against powerful financial interests. Not only does he defend his legal rights, but he also exposes hidden risk-transfer traps buried in industry contract appendices. In the end, he establishes his own risk consulting firm and stands firm on the principles of a true technical professional.
