In the chaotic last days of World War II, a small troop of American soldiers captures a German spy and learns that on a secret farm behind enemy lines, Hitler has stockpiled the world's finest purebred horses in order to breed the perfect military machine -- an equine master race. But with the starving Russian army closing in, the animals are in imminent danger of being slaughtered for food. With only hours to spare, one of the U.S. Army's last great cavalrymen, Colonel Hank Reed, makes a bold decision, with General George Patton's blessing, to mount a covert rescue operation.
