The Mysteries of Love

The story begins in the early 20th century, when policeman Sergeant TSU teams up with comprador Mr. KING in the arrest of a thief in Hong Kong.

After a thorough investigation, HANG and his team discover that the prime suspect CHEUNG WAH-CHIU was actively involved in the electioneering campaign for KEUNG years ago during the District Council Election, which makes them believe that KEUNG is perhaps trying to return the favor by providing CHIU with an alibi.

LAI is questioned by HANG and MAN PAK-CHU following the sudden disappearance of the fingerprints.

Someone warns on the Internet that the Hong Kong Convention and Exhibition Centre will be bombed real soon.

LAI goes out for dinner with ON and his family, during which an acid-filled bottle suddenly falls onto the street and injures a number of pedestrians.

The Rural Patrol Team has found some balloon debris in a tree around the hilltop. HANG and LAI go to the university to see POK.

With the help of his mates, HANG finally manages to locate PHOENIX, the girl who is believed to have slept with him.

KWAN-LEUNG's parents come to the police station to see HANG. They insist that KWAN-LEUNG's death is not a coincidence but the result of a conspiracy.

The scientific journal allows POK a one-month grace period to prove his theory.

LAI cannot believe that POK is in love with her. To make sure he has really made a declaration of love to her, she decides to double-check with HEI.

Keen to prove HEI's innocence, LEUNG dashes around the park to look for witnesses.

POK suggests having dinner with the TSUs at their home to celebrate the Ghost Festival.

LAI and her teammates have finally found the source of the cash, according to whom, the two HK$1,000 banknotes have been passed to WONG CHI-BUN, the yoga tutor recently hired by his company.

If the bomb cannot be defused or removed, the police will evacuate all the medical staff from the operating theatre ten minutes before the expected explosion.

HANG goes for a pint with his mates again. While talking about how obsessed KA has become with ADRIAN, HANG spots the guy in the pub flirting with a sexy woman.

PAK-CHU and his subordinates get into the TSE Village to look for WAI, but are shocked to learn that BONG and YEE have gone missing again.

FEI makes a call to POK revealing how LAI gets blamed for injuring one of Uncle GEORGE's guests while catching the alleged criminal.

A young lady called KAREN reports to the police that her friend FION has gone missing mysteriously.

To free KAREN from stress and anxiety, SIMON decides to bring her to Lamma Island for a short stay.
