The story is fairly basic: it starts a boy who has grown up on the wrong side of the tracks (Michael Dudikoff) but is now in the US Army gets tangled up with ninjas but has their skills himself. He is later found to have been bought up by a Japanese soldier/ninja but has forgotten his past due to amnesia (of course).
Meanwhile a black marketeer is stealing US Army weapons and hiring ninjas. Now it falls to our hero to save the day of course. So that's the story, naturally it is just a flimsy framework for a good deal of martial arts action. The action is often pretty decent and the film seldom has chance to get boring.
Naturally it is also pretty cheesy, especially when viewed nowadays. I particularly liked the evil ninja who had laser guns and mini rocket launchers.
