A flying saucer from Mars lands in Rome. The mission of the Martians (Paolo Panelli and Carlo Croccolo) is to conquer Earth through a peaceful invasion. However, when the arriving Martians come in contact with the “sweet life” of Rome: The easy way in which money can be earned and the sexual temptations, they forget about the invasion and decide to live on Earth instead of Mars. With Ciccio Ingrassia and Franco Franchi. (In Italian language).
