I suppose clarifications are in order - no, this is not the Tom Hanks starrer;
yes, the main idea is the same except that this time there are two people, a man
and a woman, and they are cast away by choice.
Joe places an advertisement in a magazine asking for a woman companion for one year on a deserted tropical island called Tuin Island (and you know better than to ask me where that is!). The ad is answered by one Lucy, and when they meet, Joe is highly relieved to see that she is a very beautiful lady. Somehow these things seem to happen only in the movies and in porn fiction.
The next part of the story is really confusing because there are two ladies who look alike; Joe marries one of them for immigration reasons, sleeps with one of them (might even be the same one for all I know), and goes with both of them to the island. Lucy is staying with Joe on the island but Janet is the one calling him 'honey' and 'darling' and other such terms of endearment. And a little later, Joe and Lucy are supposed to be husband and wife. The large number of cuts doesn't help at all, let me tell you.
Anyway, that's about all there is to the story, really. They keep bickering all the time, figure out how to fish and feed themselves and all the other usual castaway things. Only, they are not looking for a way out!
Once, when Lucy is pregnant and they are almost dying of disease, missionaries from some nearby island come and save their lives and Joe even lands a job as a handyman on that island. Anyway, they do get back after their year is up, but we aren't told what happens next. A few disjointed scenes later, we are told it's time to go. And we do so gladly.
For the voyeurs, the heroine is either buck naked or at least topless throughout
the movie. I mean, it is after all a tropical island and it must be hot. But even
that the audience aren't destined to enjoy because you-know-who played baddy again.
And there are no 'scenes' as such, to boot. This is a nothing movie - QED.
