Chandler and Monica prepare to leave for their honeymoon as Rachel prepares to tell Ross that he's the father of her baby. While traveling, Monica and Chandler become jealous of another honeymooning couple who get bumped to first class on the airplane. Meanwhile, Joey and Phoebe scheme to get inside the newlyweds' apartment after discovering that they don't have a key.

Monica turns Chandler on to the concept of taking a bath to relax, complete with scented oils and candles. Ross and Rachel toss baby names back and forth while deciding whether to learn the baby's sex. Meanwhile, Joey struggles with his feelings for Rachel.

Chandler's very curious about a locked closet by the bathroom in their apartment, but Monica won't tell him what is inside. After Phoebe convinces Monica to get a massage from her, she soon finds out that Monica makes sexual noises during the process, which makes Phoebe very uncomfortable. Meanwhile, Rachel feels her baby kick for the first time and Ross is upset when he can't be more involved in Rachel's pregnancy issues.

Monica and Phoebe bet on when Rachel's baby will be born as the due date comes and goes as Rachel becomes extremely irritable. Meanwhile, Joey invites Chandler to his big movie premiere and he manages to fall asleep during it. Also, Ross attempts to help Rachel speed things along by trying every possible method suggested by the doctor, except one.

Ross and Rachel go to the hospital to have their baby, but it's a long labor. They get stuck in a semi-private room, and many other couples come and go before Rachel is ready to deliver - the last couple being Janice and her new husband. Meanwhile, Chandler and Monica decide to start trying to have a baby, but can't find an empty hospital room where they wouldn't be disturbed. Also, Phoebe meets a handsome stranger and "recruits" Dr. Drake Ramoray to gather some personal information about him.

After Rachel gives birth to her little baby girl, she must confront relationship issues around her. So does Ross, who gets an engagement ring from his mother, while she urges him to propose to Rachel. The things, however, take an interesting turn.
