Everyone was late for lesson and very untidy. POK was very angry and punished them. During the outdoor training, MAN again played tricks on FAI who deliberately threw a red ball far away. FAI insisted to get it and won. POK was disappointed after recognizing most of them ate canned food. KONG persuaded KWUN to be their witness in order to set LUNG up. KONG invited YING for dinner but she had another appointment. However, it was cancelled and she met KONG at a convenient store. KONG revealed his love to her. YING's friend encouraged her to accept. MAN, KIT and FAI received research training but they were very careless. POK was disappointed. ICAC found that LUNG had several banking accounts and transferred his money among them frequently so as to hinder their investigation. KONG was waiting his opportunity but LUNG escaped.
