Joe accidentally takes a picture of a paper plate, which Moe and Larry submit to a magazine as an authentic picture of a flying saucer. Moe and Larry collect a big prize, but when the picture is proven to be a fraud, they're hauled off to jail. Joe leaves the boys for a camping trip, only to meet two genuine and beautiful aliens from the planet Zircon, who allow him to photograph them. Joe then gets a picture of a real spaceship, and this time he gets the fame and fortune, while Moe and Larry wind up in a sanitarium.
