The story:
An oil geologist and a female explorer are flying to a remote valley in the jungle in which the former has previously seen an impossible phenomenon: a fully-grown lion caught in a massive spider's web.

Caught in the sticky webs with only skeletons of jungle animals surrounding them, all they can do is wait...
