Bride-to-be Barbara Hale collapses into a faint while taking the altar vows. Hale learns that she is pregnant by her former husband Robert Young, who steadfastly refuses to give her custody of the unborn child. As it turns out, she isn't pregnant at all, but her reunion with Young has convinced her that she's still in love with her first hubby. Robert Hutton is the prospective bridegroom left out in the cold--but he's a nasty sort, so good riddance. And Baby Makes Three was produced for Columbia by Humphrey Bogart's Santana company.
