Nando Moriconi is a young Italian living in the early '50s Roma. He is completely crazy for everything that comes from the States. He tries to speak American-English (the most funny ever), to wear like he thinks Americans do, to walk like John Wayne, trying to eat cornflakes with ketchup... His life is a complete parody of the real American way of life, which he couldn't ever get.
