Lik-kei and Chung-ying inspect some suspicious batch of apparel. But they have not found anything. Ho-fan then wants to sort out the apparel. While he is ironing some garment, each of the trio becomes disoriented one after another. The next day, Chung-ying surprisingly sees Li-kei sleeping in the same bed as her. They have even mutually switched clothes between them. The same things have also happened to Ho-fan and Wing-yum. But the quartet cannot remember anything about last night. Chung-ying goes along with Ho-fan to undergo hypnosis in an attempt to retrieve lost memories. But Ho-fan cannot be hypnotized. Instead, Chung-ying recalls she and Lik-kei taking footage of themselves the other night. But that clip is not on her phone. W reminds Lai-yiu not to let anyone know her whereabouts. Lai-yiu then moves into the Yip household. Ming-kwan helplessly agrees. Lik-kei tells Ming-kwan to get closer to Lai-yiu to gather intelligence.
