Colussus and the Huns

King Bohlem, brother of the late Attila, reconquers former Hun territory. To secure this territory, he sends his son, Otto, and his nephew, Tharus, to forge an alliance with King Haadem, strongest of the neighboring rulers. Haadem, however, is just concluding an alliance with Kudrum, the ambitious son of a king hostile to Hun interests. To cement this alliance, Haadem has agreed to marry his daughter, Tamall, to Kudrun, but Tamall dislikes Kudrum. (imdb)
