Kong saves Shan again from an attack, but she loses her memory. Kong takes her to see Lan, who immediately identifies Shan as her missing daughter. Kong finds someone to hypnotise Shan to restore her memory, but the attempt is in vain.
Shan is attacked again and suddenly remembers her home and identity. It turns out that after being saved by Ho, Shan lost her way until she met Sun, who adopted her and named her Wan. Sun sent Wan to Canada to study as he did not want her to get involved in triads.
After thorough investigations, Kong suspects that Sun was murdered by his mistress.
