This story has been heard many times. There are some tribes in Africa that believe cameras steal a part of their souls when they are pictured and they prefer to be not photographed.
In this episode we are shown a young couple who is attacked by a group of natives who escaped from some old pictures that were taken apparently in Africa.
Most people don't like this episode. I find it a little boring that's all and that's not enough to make an episode receive such a bad rating as it has had. It must be the pace of the story or the special effects.
A good watch.
