Gene Kelly stars in three vignettes told exclusively through mime and dance. In ''Circus,'' a love triangle unfolds beneath the big top as a besotted clown (Kelly) pursues a trapeze artist who loves an acrobat. Next, ''Ring Around the Rosy'' follows the travels of a gold bracelet as it passes hands from lovers to love interests until it comes full circle. Finally, ''Sinbad the Sailor'' finds Sinbad (Kelly) in a world of cartoons, where he does battle and dances with many colorful characters.
