Prof. Walter Forrester is a British scientist working in the Akasava jungle in
South America. His assistant finds a mysterious stone, but it is stolen and Forrester vanishes, leaving him as the sole suspect. However, after a
Scotland Yard detective is murdered while entering Forrester's office in
London,
Scotland Yard chief Sir Philipp hands the case to attractive agent Jane Morgan, even though the
Secret Intelligence Service will also be on the case due to its international priority. Morgan arrives in South America under the covert identity of the young stripper wife of British consul Irving Lambert. There she meets Rex Forrester, the professor's nephew, who is also concerned about his fate and is conducting his own investigation. ==Cast==
