So this has been annoying me. It's a movie I saw recently but it's escaped u brain.
2 people are tied to chairs and made to watch increasingly disturbing scenes played out in front of them. I think they involve a killing of an animal, the whipping of a Chinese girl by a dominatrix, a murder, a rape...
Then I believe the two people have to kill each other but one survives. Then he is joined by another guy, an Asian I think. But at this point the original 'viewer' knows he's doomed as the Asian was one of the people tortured.
Now this is all misty in my memory. Some of this could be guessing.
