The Defected

LAI-KIT actively takes the blame for SHEUNG SING who was accused of eavesdropping, but HEI-WAH deliberately hands the whole thing over for YU-SUM to deal with. Understanding HEI-WAH's intention of sacrificing LAI-KIT for the power struggle, YU-SUM only launches an investigation focusing on the mole in the police force, deducing that the mole is KWOK-CHU, and LAI-KIT decides to help YU-SUM after a thorough consideration. CHIN-LEUNG and TIN-YUK arrive at Kowloon West, and TIN-YUK requests HEI-WAH to hand over CHING-LUNG's case. Meanwhile, with SHEUNG SING receiving intelligence from BING-GO, YU-SUM instantly comes up with an idea, so he asks HEI-WAH to surrender her power through a text message, to which HEI-WAH refuses. YU-SUM then storms into CHIN-LEUNG and HEI-WAH's meeting' Arranging to release WAI-KIU and CHING-LUNG, WING-JING plants a listening device on WAI-KIU. On the other hand, BING-GO arrives at the Battalion Commander's secret armoury and sees the firearms on display.
