For the highly anticipated fourth season of The Mole Gilles de Coster goes with ten unknown Flemings to South America. For three weeks traveling through Argentina, the land of gauchos and tango, and Messi and Maradona. They made a breathtaking tour, but were also test physically and mentally. The ten candidates have a common goal: all jobs do manage to earn as much money as possible. For this they rely on each other and soon creates close ties. Yet, they can't really trust one another, because the group has a traitor, a saboteur. One of them is De Mol. It's a high priority to unmask the Mol. For he or she who knows the most about the identity of the Mol on the end of the trip wins the entire cash prize.
