Contemporary American city. The Warren family and the Bush Group are two business empires spanning real estate and technology. Three years ago, the Bush Group suffered its worst corporate espionage case—the R&D data of Arthur Bush, the CEO Ethan Bush's younger brother and chief researcher, was stolen. Arthur himself then died in a car accident. The one who stole the data was Emma, an intern assistant personally promoted by Arthur and Ethan's god-daughter. After her betrayal, Emma changed her identity and married into the Warren family as "Emma Warren," becoming the stepmother of Sierra Warren. Her goal from the very beginning was the patent sample buried beneath the last piece of land owned by the Warren family—the only legacy Arthur left behind, and Ethan's obsession for three years. Yet no one knew that the truth of the car accident was far more complicated than it appeared. Arthur Bush was not dead. He lived under an assumed name, biding his time and gathering strength, secretly colluding with Emma, who was equally resentful. Two pawns, suppressed by both Ethan and Lucas, were plotting a counterattack that would sweep up everyone involved.
