This deadly implement,should it go off,it will destroy every living being in its path whilst leaving their property intact,so it's imperative that someone immobilize it at all costs. Detective Ash (Jim Kelly) is assigned to protect a woman with a microchip implanted in her forehead,which contains the key to the Ice Bomb. Soon Detective Ash is karate chopping and scissor kicking his way around town,dispatching henchmen by the bushel.
