15-year-old Corliss Archer and 17-year-old Mildred Pringle are best friends and get into some mischief together which causes their parents to fight over who is a bad influence on whom. Their fight also affects on Mildred and Lenny Archer, Corliss' brother, who elope one weekend when Lenny's home on leave from the Army. Fearing that the Pringles would want the marriage annulled, the couple decides not to tell anyone except Corliss. Then Mildred gets pregnant and Corliss is seen leading the doctor's office when she accompanies Mildred there. Mrs. Pringle heads to the Archers' with the wrong idea and tells them that Corliss is pregnant, and they assume that Corliss' boyfriend is the father. To buy them some time, Corliss tells her parents that she and Dexter are married, all the while trying to contact Mildred at every opportunity. Suddenly, Corliss' uncle, a navy chaplain, shows up and offers to give them a real home wedding right there.
