Anyway, three Japanese soliders survive the massacre and they swear to return someday. 36 years later, Rex Larson (Edmund Purdom), a rich bastard, shows up asking the survivors about the gold. He kills one of the ex-soldiers in a shootout and the next commits hari-kari. Luckily, the third, Mr. Tobashi, is willing to go along on the rich bastard's planned expedition to retrieve the gold. Along for the ride are Larson's partner, Mr. Jefferson (David DeMartin), Jefferson's daughter Janice (Glynis Barber), Tobachi's wife Maria (played by Laura Gemser, naturally) and the American adventurer Mark Forrest (Stuart Whitman), who has a drinking problem, did jail time, and has a dark secret in his past involving the rich bastard, but is the best there is at leading these expeditions. Whitman's character, incidentally, is introduced during a bar brawl that seems to suggest that American sailors are astoundingly racist and go to the worst titty bars in Japan.
Off they go into the jungle and Forrest hits it off with Janice, which is a bit disappointing for Maria, his ex-lover who wants to start things up again. The strangeness of Laura Gemser not having a sex scene in the film does not tear a hole in the time-space continuum, thankfully, and probably because she does have a nude scene. Her nude scene, incidentally is very brief, and her part in the film is minor; but you'll notice how central it is to the film's advertising! It's also sort of weird because she goes skinny dipping and then cries out in pain for no apparent reason and we're to understand that her character has been killed. I'm really just amazed that the film was never entitled "Emanuelle Goes on a Horror Safari".
As you might have guessed, characters are gradually picked off one-by-one in creative ways that eschew continuity or plot coherence, and at the end we find out who was doing it. This shouldn't be much of a surprise- after all, it is a horror safari. But, you might be surprised to find that the film doesn't become a cannibal epic. It's still got some decent gore, a few thrills, and some brief nudity. Other reviewers have complained that it's not very exciting. But I liked the throwback aspects of it and found it more competant than most of the films I've seen lately. Maybe I do need to stop watching so much crap though.
