It's a typically cheapozoid Roger Corman flick about the disappearing rainforest. The film is only 78 minutes long, and about half of it is a digression that takes place in an Indian village.
Here's the general idea. A famous indigenous environmentalist is killed. Although it is obvious that the money interests wanted him out of the way, the murder was performed with an arrow to feign an Indian attack, so the local police somehow decide to arrest a taciturn Indian who "hangs himself" in his cell after signing a full confession. There's a new plot twist, eh?
When the Indian's fellow tribesmen come for his body, a local North American environmentalist (Sandra Bullock) and a magazine reporter (Craig Sheffer) try to talk to them. They are unresponsive so, on the spur of the moment, the Americans follow the Indians up the river to their reservation.
Pause. Let's think about that. Sheffer and Bullock see the Indians paddling upstream, so they commandeer a canoe and follow. They don't know the terrain, they don't know how far it is to the destination, they have no supplies, they don't even have insect repellent, and they're in a stolen canoe paddling through the unfamiliar jungle, surrounded by crocs, snakes, bad guys, corrupt legal authorities, and stone age tribesmen.
Sheffer is shot from the underbrush, their canoe overturns, and they just decide to saunter through the rainforest in a random direction, even though night is approaching, they are soaking wet, and Sheffer has a gunshot wound. Well, as luck would have it, they are captured by indigenous people - the very ones they were seeking - and after some negotiations the tribe finally agrees to advance the plot somewhat:
1. They possess secret herbs that cure the wound
2. They perform a scientific autopsy on the guy who "hanged himself", thus proving he was dead before the hanging.
3. They possess more secret herbs that make Sandra Bullock want to make nice-nice for hours with the reporter (whom she had previously detested).
Well, now that the ice is broken, the lovebirds are constantly stealing a kiss on the corner of dirt roads, or in sleazy taverns filled with environmental terrorists and would-be competitors in the Anthony Quinn lookalike contest, and all of this romance is pursued with the same nonchalance you'd have with your best girly on the streets of London.
This movie might take the award for the most abrupt ending ever. Bullock and Sheffer are pursued by about a zillion heavily armed bad guys, including all possible legal authorities. They are trapped on a dock, machine guns to the front of them, water to the rear, with only about a minute left in the film.
A minute to resolve such a predicament?? Well, I'm not going to tell you how it ended.
The production values are execrable. The photographic quality is about equal to your dad's home movies, and the sound track is both inappropriate and cheesy. In other words, the director defied the odds and managed to make a bad script into an even worse movie.
I guess you know by now that Sandra did a dimly lit nude scene, and this is a rarity in her career, but she has said that she had her essentials taped down for this scene, so I don't know exactly what we are looking at. Maybe some Pebbles and Bam-Bam band-aids.
Incidentally, it seems there are still several minutes missing from the DVD cut. According to other comments, the original unrated cut was 85 minutes, but the unrated DVD release is 78. I suspect, however, that the clamor to restore the director's vision will be somewhat quieter than the one concerning "A Touch of Evil".
