Porky Pig decides to go camping in the Great Outdoors, bringing his neurotic cat Sylvester along for the ride. While sleeping under the stars, Porky and Sylvester are abducted by a giant, green-skinned alien buzzard, who whisks the two earthlings away to the planet Jupiter. Upon awakening, Porky is blissfully unaware that anything has happened, except to comment that "Things sure look different after a good night's sleep." But nervous Sylvester knows the awful truth, and goes to great lengths to protect himself and his master from the surly alien--who turns out to have a lot of lookalike friends.
