The staff on the train are creepy and insist that the group hand over their passports for safe keeping since valuables left in the rooms will probably get stolen. Really? Are you seriously going to give your passports to the inbred hillbilly's in the middle of Russia on a mystery train? Yes, well I don't see why that would be a problem, but then again I'm completely insane.
As the wrestlers and coaches start to disappear from the train, the remaining few search the cars and find a secret laboratory where bodies are being cut up. You'll keep waiting for the wrestlers to put up a fight and try to protect themselves from what is about to happen, but they don't. They may as well have been the math team.
