YUNG reports to the police that she had been robbed. The robber got a tattoo 'UN' on his arm. The police finds out that KEI had transferred two hundred thousand dollars to JENNY's account. KEI naturally becomes the suspect. The police then asks KEI to give statement. KEI admits that he had lent money to JENNY for the flat down payment and had sent JENNY home. However, he could prove that he was in the 15th floor when the murder was happening. The police set KEI free as they have insufficient evidence to charge him. Another murder case happened. The victim is JENNY's mother who had just arrived from Guangzhou. The police discovers KEI's finger print at the murder spot. KEI is again being arrested.
