You are special agents who got caught when you are carrying a mission as an undercover and try to escape from the enemy's base. All of you are kept in a prison
where you can not escape with your own. A rescue team is coming to save you but they can only get to the control room because they don't have access to the security system. What you need to do is to make contact with the rescue team and escape within an hour, because the enemy is going to execute you soon!
