Watch 6Teen Season 4 in Australia

Jen's mother, Emma, will be soon going into labor at the hospital while Jonesy and Jude start wheelchair races in the hospital corridors. Caitlin is forced to use a pay phone, which she has a fear of using, rather than her cell phone which she is forbidden to use in the hospital. Meanwhile, Nikki is too afraid of babies to help Jen's mother with the breathing exercises. Jen tries to be excused from work to go see her mother at the hospital, but she ends up getting stuck in many places, from having her shoelace stuck in the escalator to getting put in the slammer at Ron the Rent-a-cop's office, and when Nathan, a new boy Jen likes, helps to free her, they both end up stuck inside one of the mall's elevators.

Jen and Nathan are still in the elevator trying to find a way to get to the hospital in time so Jen can help her mom give birth. Jude unknowingly chats up with a dead body, and Jonesy becomes a clown to entertain the kids at the hospital, while Nikki is in love with newborn babies in the hospital's nursery, but she accidentally puts two babies in the wrong cribs when she put them back. She then goes to Jonesy for advice on how to switch the babies back, eventually leading into Nikki telling Jonesy that she loves him. She then disguises herself as a nurse in an attempt to switch the babies back and prevent a couple from mistakenly taking the wrong baby home. In the end Jude takes a picture of everyone gathered around the new baby, Emma.
