This implausible adventure is for every empty-headed 12-year-old boy who wants a bullet-spewing weapon of destruction. Four teen-age sons of American servicemen taken prisoner during the Korean War set out to rescue their fathers. The crew was captured on their mission to destroy an American submarine rather than have it fall into enemy hands. The four sons, ranging in ages from 10 to 22, steal sealed plans from the Defense Department to help them free the prisoners.
