Cary Grant stars as an angel who materializes in answer to the prayers of a harried young bishop, David Niven. Niven's efforts to raise money for a new cathedral have endangered his marriage to beautiful Loretta Young. Grant enters the bishop's household hoping to end the problems plaguing the family, but instead the bishop's negelected wife becomes infatuated with him.
It's wartime, and young people are rushing into hasty, sometimes unwise, marriages. But not pretty, level-headed Alice. Then she meets Joe, a G.I. on a two-day pass, and falls heart-over-level-head in love.
