Der Stich des Skorpion.

Wolfgang Stein spends years in Bautzen prison for attempting to flee the republic. He was ransomed by the West German government in 1971 and ended up in a reception camp in Unna. There he falls in love with a nurse, Anne, with whom he soon moves in together, who becomes pregnant by him and whom he soon marries. One day, an old friend, Dieter Michaelis, a fellow prisoner from Bautzen, comes to the reception center and asks Stein to work as an escape helper for his brother-in-law living in the GDR.
