I remember seeing this and it wasn't too bad. Low budget flick from Mexico which is better then other movies that are similar. It had to do with a group of friends on a hunting trip. They're staying at a cabin in the middle of nowhere when they start being attacked by a beast. Reminds me a bit of The Evil Dead movie with the friends in a cabin out in the middle of nowhere. Also they bump into a woman and there's a secret government lab. I think there's government scientists in contamination suits. It's been a long time since I saw it in 1989.Not the greatest film of all time but good to pass the time and a some scares.
