Ik Weet Er Alles Van! plot
Six candidates, led by Ruben Nicolai, compete against each other for four days in a quiz full of knowledge. Each participant has her or his own hobby; but in addition to factual knowledge, human knowledge also plays a role: the participants can challenge each other to a duel, where a large amount of money can be earned by correctly answering questions about each other's specialism. The more questions answered correctly, the more money can be made.
