A top woman pilot is preparing for her flight around the world and calls on Steve Douglas to modify the design of her plane. Steve takes more than a professional interest in the plane he is preparing for a long solo journey—as well as the lady aviator planning to fly it.

Chip dates an older woman and Robbie finds his ideas misinterpreted when the Douglas boys face the troubles of growing up. Meanwhile, Robbie tries to come up with a novel idea for the school float, and proceeds to demonstrate that teenage is just a time in life, but his speech, activities and clothes prove that it something much more, a lesson Chip also begins to learn.
