Public Wedding.

The operators of a bankrupt carnival sideshow hope to restore their fallen fortunes by staging a fake 'public wedding' in the mouth of their unprofitable giant whale. But the intended 'bridegroom' absconds with the proceeds, arranging a substitute. The bride, Flip Lane (Jane Wyman), much to her surprise, finds herself really married to a handsome stranger, whose career as an artist she decides to manage, much to his dismay.
