Over the past fifty years, Boudewijn de Groot has written and sung countless songs and turned out hits that are etched in the dutch national consciousness. His work is part of Dutch cultural heritage. And yet: Boudewijn de Groot himself remains a mystery. In the year he turns seventy, he decides to leave behind the hits that he has been singing for the past fifty years, and that form a bridge between him and his vast army of fans. In the documentary Boudewijn de Groot - Come Closer, he says goodbye on stage to his hits and he works on new, often very personal songs. For the first time, he allows a camera to come behind the scenes and into his private space. His children and his friends reflect on half a century of his life and career, and they wonder at how Boudewijn has remained such as mystery, even to them. The film goes on a musical road trip through time and sets out to discover who this introverted man really is.
