As summer vacation begins, Peepers takes a bus trip to his home town. His attempts at reading a mystery novel are repeatedly foiled by numerous talkative passengers.

Wes, Marge, Nancy, and Mrs. Gurney meet Peepers at his mother's house in order to give him a ride to the college, where he is to take a refresher course for secondary science teachers. They plan to arrive in the evening and drive through the night, but Mom Peepers is concerned that they all get a good night's sleep first. Finally it is agreed that they will spend the night at Mom's house, but they wind up talking all night and get no sleep at all.
