Watch Sadisflix. In Rotterdam, Baas (Lex Goudsmit) sells a batch of fake diamonds to a gang of international con-men. They pay in dollars: a suitcase full of banknotes is sent on a ship from Rotterdam to Hamburg. The wife of one of the gang members (played by Josephine van Gasteren – sister of director Louis) accompanies it to keep an eye on things. But the ship strands off the island of Terschelling and a race ensues between Baas, the gang, the shipowner and the insurer to get to the ship first and secure the case of money.
