"Weightless" tells the story of a special male friendship: Sigmund Jähn and Ulf Merbold are the first two German space travelers of the GDR and FRG, united in a common mission. Yet the two could not be more different. "Siggi" and Ulf come from two different systems and find themselves in the middle of a battle for supremacy in space. Here the two Germans are to play a leading role - one for the Russians, the other for the Americans. (MDM)
