A robbery case subtly interweaves the fate of three strangers, a barrister in a wheelchair KO CHIT-HANG (Kwok Chun On), a Hong Kong girl TAM MEI-CHING (Kristal Tin) and District Crime Unit detective CHEUNG LAP-FAN (Ron Ng). Implicated by her gangster boyfriend, MEI-CHING is charged with attempted robbery and is found guilty.  Although CHIT-HANG, as the lawyer representing MEI-CHING, fails to exculpate her from the charge, the two fall in love with each other.  Gradually, under CHIT-HANG’s guidance, MEI-CHING manages to turn over a new leaf after getting out of the jail.  Through his investigation, LAP-FAN learns that, many years ago, he negligently shot and thereby paralyzed a civilian, who turns out to be CHIT-HANG.  Instead of bearing a grudge against LAP-FAN, CHIT-HANG turns into his best friend.  CHIT-HANG has been abandoned by his family ever since the accident.  In order to make a living, it takes him more effort than the others to eventually stand out and become a rising star in the legal profession.  Being recruited by  wealthy businessmen, MA KAI-YUEN (Louis Cheung) and TO YEE-HANG (Waise Lee), CHIT-HANG often claims victory in lawsuit cases by surprise tactics, helping set his clients free.  However, there is evil hiding behind his decency.  The more successful CHIT-HANG becomes, the more suspicious LAP-FAN gets.  All of them, including MEI-CHING, seem to be trapped in the slowly tightening grip of encirclement one after another, finding themselves on the horns of a dilemma……
