Guerilla Hellcats (1968)

Under the mundane guise of a public relations firm, Singrid Karaman is actually running an intelligence network. Her new mission is to foil an upcoming coup attempt in the African country of Myassaland, and to recover the large stock of diamonds that have fallen into the hands of the mercenaries behind the plot. She instructs a former Nazi, Eric, to form a shock commando and her assistant, Carol, to contact the mercenary leaders, Commandant St Robert and Captain Tarquier. Although Tarquier is very suspicious, St Robert agrees to go aboard Ingrid's yacht.
