Ronan Shaw built the "Yuanshu System" for Yucheng Tech. Credit stolen by superiors and colleagues, bonus zero. System crashes. Executives beg for help. Ronan Shaw sets three conditions to return. He fixes the system, uncovers a corruption scandal: a general manager embezzled funds. At a Board meeting, he uses evidence to expose counter-accusations, ousting the manager. Ronan Shaw is promoted to Chief Technology Officer. He reshapes the Tech Department with new rules, completing his comeback.
