A mysterious and colossal flying cake appears in the sky on the outskirts of Rome: a group of children of inhabitants of the township approaches it and, gluttonous as children are, takes away pieces of chocolate and other fragments. The appearance of the bizarre flying object puts civilian and military authorities on the living and even raises the concern of an avid candy tycoon, who fears UFO competition. After attempting to scare the population with the false news that the cake is poisoned, it is denied on live television by the children, who flee the control of the authorities and reach the cake again, reappeared and landed on the top of Monte Chicco.
