In the new SBS6 program Graf Zonder Naam, Kees van der Spek goes in search of the stories behind the anonymous graves in the Netherlands and tracks down the next of kin. Spread over the cemeteries in our country are about 300 people whose identity is unknown. The anonymous dead. This means that there are also 300 families who have often been waiting in vain for many years for a sign of life from their missing child, brother, sister, father or mother.
