Known or unknown, taking risks or playing it safe, walking familiar paths or exploring new horizons. In The Unknown, a new adventurous waste race devised by the makers of De Verraders, Axel Daeseleire takes a group of candidates on a journey. During their adventure they are constantly challenged and have to choose between 'the known' or 'the unknown'. The game can take an unexpected turn at any time, causing emotions to run high. Who dares to choose the unknown path in an adventure program where no one knows what the rules are? And what yields the most: known or unknown? In the end, only one person will go home with the cash prize.
