Synopsis：After three years away, Grant returns home with a brooch for his sister Ella—only to watch her plunge to her death from the top of Vanguard Tech. With her last breath, Ella reveals that Kane engineered her ruin, stole the company she built, and drove her over the edge. Grant gives himself three days to take revenge. At the merger celebration, he quietly unleashes his deadly skills—while his in‑laws, the Richards family, and other relatives mock and belittle him, unaware he has just been sworn in as the new FBI Director. As Grant shields his wife Laura and dismantles Kane’s conspiracy piece by piece, he hunts down every culprit and fights to reclaim the empire his sister forged with her own blood and tears.
