I'm sorry but I can't make a synopsis of the programme,whilst it's being aired, every time I post.
However, 3 of them had to answer questions, and another three had to electricute them if they answered incorrectly. They were screaming with pain and it was awful. In the end the tortureres said we cant do this it's horrible. But the twist was that the three screaming in pain were acting and it was their task to get the other three to stay no stop, we can't do it anymore, so the task was passed.
