Big Brother turns nasty when 5 strangers apply to live in a deserted, isolated mansion for 6 months while they are filmed 24/7.  If they make it to the end, without anyone leaving, they win $1million.  But it's not going to be that easy...

After they stumble onto the website, which isn't being marketed as they hoped, and see the betting odds on each of them making it out alive, Matt (Sean CW Johnson) goes mental and starts killing them off.

First he suffocates the flirty girl who got it on with Bradley Cooper earlier, and then the curly haired Rex gets up in the night and sits down infront of the PS2. Matt steps out with a wild look in his eyes -- and decapitates the guy with a clean swipe of an axe he found.
  Next, he chases the remaining victim (Charlie) all around the house.  They both beat each other pretty bad - but she makes it out alive just as a patrol car turns into the drive.
  The policeman sees the blood on her, handcuffs her, and puts her into the back. He then apprehensively enters the house, gun drawn.
  He exits soon with crazy Matt, but then its obvious that the cop is in on it as well.  Charlie gets out the car and makes a run for it.
  The cop takes aim, shoots, and she falls.

It cuts to the kitchen, and Charlie locked away in a freezer, still alive.  The cop and Matt are both chatting - and Matt wants a parking space when he starts work for 'the company' again.  Matt gets up to take a look at the victim - but then his brains are blasted all over the freezer door.  So all bets are off, Charlie was the last one standing.
