Anita's (Loretta Young) life seems to be progressing nicely. She's engaged to Don Barnes (Broderick Crawford), a wealthy man that will give her all the stability and comfort a woman could desire. But then she meets a magician with the unlikely name of The Great Arturo (David Niven), who performs a singular feat of magic -- he sweeps her off her feet.
Promptly dropping Barnes, she weds Arturo and travels the globe as his assistant. After some time, however, the magic begins to wear off and Anita longs for a simpler life, perhaps on a quite farmhouse in the country.
She's also a bit put out by Arturo's flirting with other women, but what really worries her are the dangerous stunts he has added to his repertoire. Realizing it is time for her to do something, she pulls a little magic of her own and disappear, forcing Artuto to set off on a lively chase to find her.
