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 assistant, an eager young space cadet (Porky Pig), crash their spaceship into a giant egg-shell, where they find Marvin Martian, who is, as usual, scheming to destroy Earth. Marvin asks Dodgers to visit the boudoir of Gossamer, a giant, hairy monster in sneakers, and the frightened Dodgers flees. Porky uses electronic clippers to literally haircut Gossamer into nothingness, and Dodgers, jealous of his assistant's heroism, repeatedly fires his ray gun at Porky's rear.
