Let's say Erin (You're Next) and Kevin (Home Alone) had 24 hours to booby-trap a mansion sized house, and then you had to survive in that house while collecting keys (scattered throughout the mansion) to unlock the door and leave. Do you think you could do it?
Let's say you needed 6 keys that are randomly paced throughout the house. And before you ask, all windows are barred off, their is no means of escape besides the locked front door. How long do you think you'd last?
That sounds extremely painful. Both of them trap to mutilate and cause pain, I'd probably die from bloodloss.
