The Twins Effect (2003)
Legend has it that if a vampire absorbs the blood of all six princes of the ruling class of each vampire nation, he will open a path called “Day for Night” from the vampire bible, which essentially allows him to walk in daylight freely; thus becoming invincible. The Guild’s top vampire hunter, Reese (Ekin Cheng) has hunted The Duke of Dekotes (Mickey Hardt) back to Hong Kong, where the Duke intends to find the last and final prince, Kazaf (Edison Chen), to open the “Day for Night” passage.
On arrival, Reese learns that he has been assigned a new partner by the Guild – a feisty yet inexperienced young girl named Gypsy (Gillian Chung), and matters are further complicated when Reese’s baby sister, Helen (Charlene Choi), develops a romantic relationship with Prince Kazaf. And things really go from bad to worse as the Duke Dekotes captures Reese, leaving the fate of the world in the hands of these two inexperienced teens…
