Though she can spin wild tales of passionate romance, novelist Joan Wilder has no life of her own. Then one day adventure comes her way in the form of a mysterious package. It turns out that the parcel is the ransom she'll need to free her abducted sister, so Joan flies to South America to hand it over. But she gets on the wrong bus and winds up hopelessly stranded in the jungle.
This film does make you realise just how good Harrison Ford was in "Indiana Jones" (also 1984) and how good Danny DeVito is in this - but as far as Michael Douglas and Kathleen Turner go, well they are really pretty mediocre. He is "Jack", the dashing rogue who ends out helping slushy fiction writer "Joan" through the Colombian jungle in search of her kidnapped sister - something about a treasure ...
I guess I was a bit more impressed with the leads in this movie than the other reviewer here, for I think they held up their end of a story that is, if anything, even more of a take-off on action movies that the Raider franchise. It is fluff, of course, with odd violence offsetting what is a rather gentle adventure. Good luck finding it on one of the streaming services out there. It is for sale...
