Bassie & Adriaan go in search of a package in Germany, which Bassie likes because he fancies a trip along the Rhine. But Bassie doesn't realize that Handy Harry has built a transmitter into his Walkman and that the crooks can now follow him on a special screen. The crooks also see that Bassie & Adriaan are traveling to Greece. There, they have to track down a package with the help of a sailboat. This allows them to see a lot of Greece, but they don't know that there is a diver under their boat, which could be very dangerous!
