Gamers from all over Holland have gathered at a game convention to find out about the latest game. After the convention, most of the gamers go home, but for a few of them, the night has just begun. They have all received text messages saying that they should stay in the building after everyone has left and play the game. Since the prize money is 1 million Euros, they all decide to stay. What they do not know is that the subject of the game is surviving; in real life. They soon realize that they are trapped inside the building with a serial killer after them.
