Lila is a crew member of a light-speed test flight taking place at the turn to the next century. She and friend Charlie go beachcombing and meet Rupert Metzger, the rocket designer. Their experience goes to taking considerations of outer space plotting from seashores, given of natural designs.
In the process of considerations of rocket design, the flight to test the rocket takes place and lands the crew member, Lila, with her friends, who continue beachcombing. Beachcombing continues with considerations for navigating through outer space, returning back home, and beachcombing.
