It was directed by Kurt Maetzig, and stars Günther Simon, Julius Ongewe and Yoko Tani. The film was first released by Progress Film in East Germany, running 93 min.

After finding an ancient, long-buried flight recorder that originally came from a spaceship, apparently from Venus, a human spaceship is dispatched to the Morning star. The crew discovers a long-dead Venusian civilization that had constructed a device intended to destroy all life on Earth prior to invasion. Before they could execute their plan, they perished in a global nuclear war.
