Inspector SUN CHIU-TUNG (Liza Wang) leaves the police force because of an unsettled case. She then opens a private investigation agency and, due to all sorts of accidental mishaps, employs KUNG CHAK-LAM (Wong Cho Lam), KUNG TUK-LAM (Louis Yuen) and TSUI SHUI (Johnson Lee). The three young men have all been treated badly by life. By taking them in, TUNG is given the ability of clairvoyance, that is, the power to see the future. CHAK-LAM, TUK-LAM and SHUI also have distinct supernatural power of their own. CHAK-LAM can go through a wall; TUK-LAM can turn into a kung fu master for a minute whenever he likes; and SHUI is able to make a person tell the truth. With their supernatural powers and superb impersonating skills, the foursome is gearing up to crack the most difficult cases and make you laugh and fall off your chair!
