Without a Trace - Season 41
9.50 50 minutes Spoorloos is a television program of the KRO-NCRV in which tracing blood relatives is central. Sometimes family members have lost track of each other, or have never even seen each other. The reasons why contact is broken are diverse. For example, a child who has been abandoned by one of the parents after a broken relationship or a baby who has been given up for adoption. These often concern sensitive matters that require the editors to proceed cautiously. The presentation is in the hands of Derk Bolt. He regularly goes out to track down family members.
