Binky the Space Cat has been assigned an important mission: to train a new space cadet recruit. But when the youngster named Gordon shows up at Binky's house, he's not a kitten at all. He's a dog! Ever dutiful, Binky and his colleague Gracie give it their best effort to train him, but Gordon just seems too simpleminded to be up to the task. It's not until they've nearly given up in exasperation that the two cats learn the surprising truth about Gordon - he's not the dimwitted dog they thought he was!
