The founder and first emperor of the Ming Dynasty, CHU YUEN-CHEUNG have just passed away. CHU WAN-MAN (Chan Shan Chung), who is the son of his designated heir, is made his successor.

MAN's bodyguard NGO SIU-FUNG (Michael Tse) is ordered to search for CHEUNG's lost will and in the course of his investigation, he gets to know the Prince of YIN CHU TAI's (Joe Ma) counsellor, MA SAM-PO (Sammul Chan).

FUNG and PO appreciate and respect each other, but FUNG reminds himself not to drop his guard, as TAI is coveting the throne of MAN.

One day, FUNG loses his memory during a mission and has turned from a cruel person into a sympathy filled man. PRINCESS WING-YEUNG (Elanne Kwong) has never liked or trusted brocade guards so she tells PO, a good friend of hers, to guard against FUNG.

MAN still thinks very highly of FUNG, but FUNG has become distrustful since his accident and for a reason he does not know, he finds the mysterious SHUM TSIN-SAM (Kate Tsui) and TAI, to be familiar.

Later when he comes to know a secret mission, he is caught in a dilemma of anger and guilt.
