1952: Jungle Jim in the Forbidden Land

Denise (Jean Willes) is a Fortune Huntress, who will stop at nothing to gain wealth...

Under the pretense to help the natives, she fools the authorities into letting her take an expedition into a land full of valuable ivory tusks attached to elephants...

Jungle Jim refuses to help her, so she has him knocked out...

And then shot up with a truth serum drug, causing JJ to spill all the beans...

She then has him knocked out again ("Oh, Jungle Jim won't mind...")

Her henchman remarks: "You're a cold-blooded proposition..."
