Daffy Duck reprises his famous role of Duck Dodgers in another spoof of Saturday afternoon space serials. Assigned to locate the rack-and-pinion molecule needed for yo-yo polish, Dodgers and his sidekick, an eager young space cadet (Porky Pig), crash their spaceship into a giant eggshell-shaped planet, where they find Marvin the Martian, who is, as usual, scheming to destroy Earth in an attempt to solve the "energy crisis". Marvin asks Dodgers to visit the boudoir of Gossamer (Looney Tunes), which Dodgers thinks is a space princess, but Gossamer turns out to be a giant, hairy monster in sneakers, and the frightened Dodgers flees. Porky uses electronic clippers to literally haircut Gossamer into nothingness, and Dodgers, furious of his assistant's all-too-literal interpretations of his commands, repeatedly fires his gun at Porky. When Porky asks what Earth will do without the rack-and-pinion molecule Dodgers replies "Let them eat cake."
