American Ninja 2: The Confrontation

Soldiers Dudikoff and James are back again using their martial arts skills (in lieu of any acting) to take on a Caribbean drug-lord. Apparently he has been kidnapping Marines and taking them to his island, where he genetically alters them to become fanatical ninja assassins eager to do his dirty work. The script hardly gets in the way of the rib-crunching action, but is an improvement upon Ninja Number One.
