My Lucky Stars

Two Hong Kong cops are sent to Tokyo to catch an ex-cop who stole a large amount of money in diamonds. After one is captured by the Ninja-gang protecting the rogue cop, the other one gets his old Orphanage gang, dubbed the "Five Lucky Stars," to help him. They travel to Japan and infiltrate the yakuza group's lair, using their wits and martial arts skills to outsmart the thugs and finally bring the ex-cop to justice.
