Every year thousands of dancers come to Columbus, Ohio, to compete in the world's biggest ballroom dancing competition. They represent many age groups and dance styles. They come for only one reason -- to see if they have what it takes to be the very best. For those who win their divisions -- the grand finale will be their last test. When they face off against the other division champions in a winner-take-all battle for the ultimate title of "America's Best Ballroom Couple." The program is hosted by Jean Louisa Kelly.
