Adam, Evchen, and Manni are looking at the moon through their home-made telescope. Evchen isn't interested, and dismisses the moon as a lump of cheese. Manni, who is a big fan of technology, sees satellites and a car driving over the moon's surface. But Adam hears the moon speak, and hears it ask for flowers to cover its surface. From then on, Adam is determined to breed a kind of flower that can grow on the moon. Although he is made fun of at school and is yelled at by his father, who develops extra-nutritious vegetables for Professor Vitamin, Adam keeps trying. Eventually things take a positive turn. Kondensmaxe, in his airplane, finds Professor Vitamin's old magic greenhouse. It turns out the Professor was herself concerned with developing such a flower, before the war, and is willing to assist Adam in his research. Manni and Evchen support him every step of the way, and so does Adam's grandfather. Eventually Adam's mother even convinces her husband to assist the children...
