Golden, the great diamond magnate, is murdered. The only evidence is a photo taken by two journalists, Franco and Ciccio. These two later receive a mysterious invitation to come to Amsterdam, where they must contact an Indian Guru and David.

Their attention is then somehow drawn to the Hotel Alpha where - whenever they snoop around - they are treated like troublemakers.

They manage to flee but later find out that they have unmasked a gang of smugglers...
