Drie Recht, Één Averecht plot
Bertus de Vries, a somewhat unreliable businessman, owns a large building in the city in which he opens a gym. He has all the courses taken care of by former gym teacher Wendy Keizer, while he does some other things himself to earn extra money. He rents out the top floor to three recently graduated lawyers: Laurens Jan Bolsenbroek, Lex Tiggelaar and Gon de Swaan. The lawyers and Bertus often have differences of opinion, because they think differently about what is and is not allowed.
