Kate is cleaning out the storage closet, and wants all the family members to go through their belongings of the items in the closet. Although no one is around when Kate starts the job, she manages to find Uncle Joe (who wants to start an antiques business with his junk), Billie Jo and Bobbie Jo, but Betty Jo, who should have have been on the afternoon Cannonball run from school, isn't around. Kate receives news from Floyd and Charlie that last they saw Betty Jo that morning, she, all made up and with suitcase in hand, looked like she was about to run away to elope. Worried that Betty Jo has done something foolish, Kate, with help from the other girls, look for clues in Betty Jo's room and find that if Betty Jo is indeed planning to elope, the groom's name is Peter Latimer, a new boy in town. Kate does what any concerned mother would, and that is to rush off to find and stop Betty Jo from getting married.
