Jungle Queen (1945) is a Universal movie serial.
This serial was later re-edited into a feature film for television called Jungle Safari (1956).
In 1939, Nazi Germany sends a team of agents to incite revolt and seize British Middle Africa as a first step in conquering Africa.
Attempting to place their own sympathiser in charge of the local tribe, they face resistance from Pamela Courtney searching for her Uncle Allen Courtney, a pair of American volunteers and the mysterious Jungle Queen Lothel, who appears out of nowhere in her nightgown to give advice and instructions to the tribe.
Cline writes that "although well produced, it often became bogged down with complicated plot twists, psychological debates and confusion as to who was on whose side, and what was really being accomplished."
