I'm trying to remember a movie I watched years ago. The base plot is similar to that of the running man, the tournament and hunger games, and house of nine. With the whole survelliance n people watching stuff like that. There is a group of people who have to survive against several killers to win a cash prize. The ending is a girl wins but it turns out there's more to it because other people won. But they only move on to another part. Please help me I'm in dire need to know
