A Disney movie for the kids or whole family. An American businessman goes to a South American island to finalise his divorce from his estranged wife, having been seperated for 13 years, so that he can marry his current girlfriend.
There he discovers he has a 13 year old son, raised as an Amazonian Indian, and he ends up taking his son back to New York, to his 'village in the jungle'.
Sounds like the Disney version of Crocodile Dundee, with lots of slapstick humour.
