An American astronaut named Dmitri splashes down in the Atlantic Ocean after spending two and a half years on the Moon. He is picked up by the cruise ship S.S. Knickerbocker and sails to New York City, but quickly realizes that no one remembers him. Dmitri visits the Museum of Intergalactic Exploration, where he is so discouraged by the neglected state of the museum's Moon exhibit that he tosses his collection of Moon rocks into a trash can in Central Park. Dmitri does not know that his friend Lulu, a small pink creature he found on the Moon, hid inside the bag of rocks before Dmitri took off for Earth. Dr. Geoffrey W. Beaton, a Nobel Prize-winning scientist, finds Lulu in the park and takes the creature to the Academy of Science. The following day, Dmitri finds Lulu at the Academy, where the creature has covered the walls with crayon drawings of Dmitri in his space suit. Dmitri is finally recognized by Dr. Beaton, and Dmitri and Lulu are hailed as heroes.
