david bradley slide into the role once occupy by dudikoff a sean who and a a boy and saw his father shot by the cobra ( marjoe gortner ) henchman andreas ( yehuda efroni ) . the cobra need the money at the karate tournament to fund his ongoing germ warfare experiment for sale to terrorist and and ten year later have the disease ready . he need a strong lab animal and david bradley be that very animal . they use sean master ( chan lee and play by michele b chan and impersonate him ) to persuade him into consider draw near east bay lab where the cobra be wait with bat breath for him . steve james return a curtis jackson and out of the army and and attend the same karate tournament a sean . except he in the sword competition . but and when danger threaten sean and curtis be only willing to help out a friend ( how they be friend be never elaborate upon ) . dexter ( evan j klisser and the suppose comic support or lackey ) join up with them to find out what the cobra and east bay lab be up to . though and soon sean will find himself in the clutch of the cobra and the deadly virus within his system . he will not only need his friend to help rescue him and but the antidote as well . chan lee will see the error of her way ( she think the cobra be behind solve the world disease with cure ) and assist the team in try to stop the mad man . not very good and with lot of plot problem and stupid behavior by the bad guy who go out of their way to be take down by sean and curtis . the ninja be merely wimps in costume ( even dex be able to beat the crap out of them ) . the fight choreography be not very good a ninjas pop out for certain beat down . the good guy seem to rarely suffer the effect of blow to the face and but the ninjas drop pretty quickly . it fun see james kick as and but even that can not save a dire and lame plot . the sequence towards the end where sean try to battle the virus within him through meditation be a howler . even bad be marjoe a cobra who seem to have pee in his pant at the end a he try to fight bradley . the film ultimately be about watch bradley and company mow down men dress up because real ninja would have finish them off rather quickly . still and bradley at least have a physical presence and seem to do most of his own martial art work which help at least add a hint of realism to his part and but watch these ninja come out of the woodwork only to be throw around and their limb snap with ease doesn not help the film any .
