Three couples, each newly expecting a child, have different but familiar reactions.
Lizzie and Danny are university juniors who have just moved in together. Athletic Pam and her husband, Nick, a sports instructor, have had some trouble conceiving. Arlene, already the mother of three grown daughters, is unsure of what to do, while her husband Alan is thrilled with the thought of a new baby.
Throughout the show these characters experience all the emotional stresses and triumphs, all the desperate lows, and all the comic highs that accompany the anticipation and the arrival of... a baby.
