Ngo was found not infected with AIDS. Eight years ago, when Mon was still a club girl, she met Sing and the two became lovers. She then discovered that Sing was a wanted robber. He asked Mon to open a safe at the bank for him and deposited most of the stolen items into it. Then he had to flee to another country. Since he had the key to the safe, Mon could not lay hands of his treasure. Mon tried to send her men to take the key from Sing, but he managed to get away and during the confusion, Yuen’s sister Fuk was shot. And the key to the safe accidentally fell into Fuk’s hangbag. Mon then sent her men to Fuk’s house, tied up Yuen’s mother and her other sisters, and turned the house upside down for the key. Their search was discovered by Sheng and Ngo and Ngo managed to catch one of the fleeing men. When Yuen learnt about this, she was furious and went directly to Mon’s night club without a warrant and tried to have a routine check.
