Conceited film star Emery Slade was on top in 1932; in 1949, he's broke and still insufferable. Fox producer Crossman enlists Slade's aid to persuade broadway star Rosalie Brooks to star in the film "Bandwagon." But when Slade meets Julie Clarke, his assistant's onetime girlfriend, he decides she, not Rosalie, should get the part. No one can fathom his motives for this apparently selfless act, but there are a few tricks in the old fox yet...and he'll need them all.
