Basically, it seemed to be a game show that involved torture. For instance, the first round involved someone crawling through barbed wire. The second round involved rabid dogs chasing after someone on an assault course. Then for some reason there was a round where people had to guess classical music, with anvils being dropped on various limbs if people got it wrong.
And after that, I woke up, confused and wondering if this game show is already on Japanese TV.
