There should be a genre for “two people in a torture room” thriller. Occasionally you see these movies with the same theme: somewhere betwenen two and a handful of people stuck in a closed room, enduring some sort of experiment or game where they see how they tolerate torture. This is one of those. A woman plays an endurance game that starts with seeing how long she can hold her hand over a candle, proceeds through having to cut the last digits of her own fingers off, and ends with Russian Roulette. In this case, the characters don’t even have names. Eh. The woman was good.
