In the new show "De Erfgenaam" ["The Heir"] Ruben Nicolai searches for the rightful heirs of deceased persons who leave behind an inheritance, the heir to which is not found. Ruben is aided in his quest by inheritance law expert and genealogist Klaas Zondervan. Nicolai seeks to uncover the family stories behind these unknown inheritances, a journey that takes him all over the world, producing moving, funny and poignant moments. His goal is to deliver the funds to the rightful heirs before they become time-barred (after 20 years) and disappear into the Dutch Treasury.
