Chan Kong-Ho

A motley group of Chinese prisoners held in the US is sent on a covert mission with the promise of a pardon: to go deep into Vietnam and destroy a secret depot of missiles that the US left behind during the pull-out.

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 don't like this much, but they do it.
