Men Behind the Sun...

They explain it much better than I can. I like the story line, although there isn't much of one and the gore factor is off the charts. Also, apparently they had a room full of rats and than threw a live cat in the middle of it and the cat is torn limb from limb by these rats... it's a pretty disturbing sight to say the least
