The old 50s bait n switch strikes again!!
Starts with stock footage of rocket launches, quickly becomes a trudge through a handful of jungle sets.
When a rocket crashes in Mexico, an expedition to find it vanishes. The wife of one of the explorers hires guides to find her missing husband and heads into the jungle.
In the last reel things get more science fictiony when they make a shocking discovery!
I've seen lots worse, at least the story moves in a sprightly fashion and the rather basic characters are acceptable. The hour and 12 minute runtime helps!
