Marlo Thomas plays the title role; a young small-town woman, who moves away to the city when she becomes pregnant through a one-night stand. She meets film director Delano (Alda), who has received a draft notice and does not want to be inducted into the Army. Jenny and Delano take a liking to each other. Learning that an acquaintance got out of having to serve by having a baby on the way, Delano offers to marry Jenny, claim paternity and support her baby, if she in turn will play along, and he can avoid being drafted.
The movie follows the months until Jenny's baby is born, and the ups and downs of their in-name-only marriage (including a visit back to her family and hometown, and his ongoing relationship with another woman), as Delano and Jenny await the outcome of his draft case.
