twin brother separate at birth ( due to the death of their parent ) reunite twenty five year later to avenge their parent and take back their million dollar tunnel . double impact run at two hour long and basically add no real approach to the corsican brother plot and jean claude van damme while adequate a the evil twin brother be just embarrass a the good twin brother . also the action sequence aren not a excite this time and jean claude relies more on gunfire then on his martial art . also the support cast be waste and at two hour the movie be just plain dull . out of 4 ( bad ) .
