Popular OBC radio emcee Buzz Fielding (Bob Hope), who has just been released from “alimony jail” and is broadcasting live from the "Gigantic", is trying to juggle his three ex-wives Cleo (Shirley Ross), Grace (Grace Bradley), and Joan (Lorna Gray); his lukewarm girlfriend Dorothy Wyndham (Dorothy Lamour); and his inept microphone assistant Mike (Ben Blue). Buzz does his best throughout the voyage to announce the progress of the race and introduce a series of musical acts for the pleasure of the passengers and OBC’s radio audience.
