The Vale of Darkness was presented as "a story of violence and intrigue".  Written by Ron Evans, the story centers around a group of escaped soldiers from various countries and civilians from internment camps who are fleeing from the Waffen SS.  The Nazis sent three divisions of SS to Yugoslavia to take care of the Yugoslavian underground. Mistakenly directed by British Intelligence to head for a pass in the Montenegro Mountains where the going is very difficult, another group of British soldiers is sent to rendezvous with the ragtag group and lead them to safety.

Vale of Darkness ran for 30 episodes on the South African Springbok Radio network.
