I saw the trailer yet while watching letters.
Abit lame.. but this show alot of old birds. 
A Dzi bead from Tibet was on its way to Hong Kong for an
exhibition, but was stolen by a mysterious gang with a possible
link to a long-lost cult, the Gemini Clan. The guardian of the Dzi
bead, Lucky and his adopted son, Hey tried to solicit the help of
the head of the Clan, the Principal, to track down the bead.
Unwilling to come out of retirement, the Principal refused to get
involved, but when Lucky was seriously wounded after another attack
by the mysterious gang, the Principal reluctantly summoned the help
of the Clans former member Twins.
In the meantime, the suicide of an artifact dealer put the police
hot on the heels of the Principal and his students. When Hey
finally retrieved the bead, he mistakenly handed it to the
Principals twin brother, the Boss, who was the master mind behind
the theft in an attempt to take over a prime piece of property
along the coast.
