This was a competition game show on TNT. It's not really a reality show whatever that means nowadays. Three teams of two compete to escape a prison scenario using maps and clues. There are guards that could send the teams back to the beginning if they're caught. They try to gather pieces to unlock the final suitcase full of money.
It's actually pretty fun to watch especially for the first half. That's when the three teams start off together, and there's a mad scramble to get out of the starting imprisonment. But after awhile, the teams separate and it's just not quite as compelling. The competitions don't always have enough back and forth. But it's still watchable.
