Twins Mission

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 Clan's former members - twins.
