Tooske Ragas, Wolter Kroes, Annemarie Brüning, Tommie Christiaan, Hannelore Zwitserlood, Julia van Reyendam, and Jamie Westland are guests at the historic Zuiderzee Museum. They will be attending the christening of a real Texel blazer. But before the champagne bottle can be smashed against the bow, one of them is murdered.
