Financial elite, CHEUK YUK (Bosco Wong), never hesitates to use any dirty tricks to gain a profit, so he has been under close surveillance by the Commercial Crime Bureau (CCB). Being obsessed with money and power, CHEUK YUK constantly neglects his family members and friends. Because of him, his wife and mentor pass away respectively, yet he shows no remorse at all. On the contrary, his craving for money and power continuously increases. His brother-in-law CHOW SUN-YUNG (Ben Wong), one of the CCB inspectors, is determined to put him in jail, collaborating with superior HO SHEUNG-YEE (Sharon Chan) and subordinate CHI NGA (Kate Tsui) to gather evidence. SUN-YUNG thinks highly of CHI NGA and even regards her as his last apprentice, to his surprise, CHI NGA suddenly resigns and starts working for CHEUK YUK. At first, she gains CHEUK YUK’s second wife, FONG MING-YU’s (Nancy Wu) trust, following which she helps CHEUK YUK deal with CHAI PUI-FUN (Elena Kong), a mogul in the financial industry. It seems that CHI NGA has grasped total control, undermining CHEUK YUK’s ambition. Who will eventually be the ultimate winner when facing fierce competition in the financial battle like this?
