Nell Carter is your hostess for a fun-filled fling in the center ring of the Greatest Show On Earth.  Thrill to hair-raising heroics of MARGUERITA AYALA and her lovely daughters; tumble and twirl with teeterboard titans, the HELICON TROUPE; fly through the air with the GUTY FAMILY; bark your troubles away with JOHNNY PEERS and his comedic canines, and meet the newest star of Ringling royalty, Italy's great FLAVIO TOGNI and his animal all-stars.  All this and more in the last-ever televised highlights of the mighty RINGLING BROS. and BARNUM & BAILEY CIRCUS - the 120th Edition, from sunny Florida.  Approx. 50 minutes, color.
