It's a game show in which contestants have to battle their own fears in total darkness. Not just dark. Completely dark. We can see what they're doing through the magic of night-vision cameras, but they can't see anything at all.
It's great fun to watch them get scared. Because a lot of times, they're scaring themselves.
