During the war with Nazi Germany several Allied units reported coming across SS units that were virtual killing machines and would fight only with their barehands. It would seem that Nazi scientists experimented on the bodies of German soldiers killed in action. The individuals of course were the absolute worst sort (sadists, murderers, war criminals, etc.) and that is saying alot seeing it is Nazi Germany! These individuals were given a unit entitled Toten Korps ala the Death Corps. This experiment had some success but these quasi zombie like SS soldiers were uncontrolable and were pulled off the battlefields for further study. As the war was drawing to a conclusion the last remaining squad of Toten Korps was put to sea to await further orders which never come. The commander (Peter Cushing) scuttles the ship. The ship and her 'cargo' are condemened to the ocean floor....for now anyway!
The movie starts off many year later with a boat load of tourists and crew who happen to ram the old wreck stirring up its 'cargo.' The crew and passengers take refuge on a nearby deserted island populated only by the former SS Commander Peter Cushing who is in hiding. Naturally the SS zombie soldiers lay siege to the island and begin picking off the crew and tourists.
That is Shockwaves in a nutshell. The plot is great and it is what makes this movie. The acting is good for a B movie and it does create an erie atmosphere. I would recomend it because it is unique. This is not a run of the mill zombie flik with buckets of gore and pathetic special effects. This is , again, a well done B-movie! Thumbs up on this one!
