The show travels around the world showing the beauty and uniqueness of foreign countries and cultures, it's got the game element, it has the big brother reality TV component (how well do the teams work together under pressure?), and then there's the once in a lifetime factor that you get to experience with this group of people. Most of the couples even when eliminated will tear up and be thankful for the experience. And of course us viewers can go along for the ride sitting on our couches (and hopefully get motivated to travel and experience those things first hand).
What's the show about?
