Kip from midwest Centerville USA works the summer before college as a pharmacy soda jerk, and wins an authentic stripped-down spacesuit in a soap contest. He answers a distress radio call from Peewee, scrawny rag doll-clutching genius aged 11. With the comforting cop Mother Thing, three-eyed tripod Wormfaces kidnap them to the Moon and Pluto.
