She and Ching Fung (Marco Ngai) are also now parents to a pair of girl/boy twins, but their marriage is not as happy as it seems as the two continue to have quarrels in their marriage. With marital problems at home Sam Yuen becomes a cold, unreasonable and mean boss at work. When a case similar to the psychotic serial rapist in the last series arises Sam Yuen starts feeling threaten and her trauma which she thought she conquered starts to set back in, making her obsess over the investigation. Even though the culprit Bao Gwok Ping is still locked up in jail, he seems to have been communicating with someone on the outside who agreed to take on his split personality persona and continuing his crime spree.
