Eerie encounters during a summer sailing trip cast their shadows ahead, and as skipper Claus and his female DODI crew spend their summer vacation with friends on the canals of Holland, they come face to face with horror. Everything is a bit different on the canals of Holland, and chaos reigns all the way to Groningen. Friend Kalli discovers a coffee shop, daughter Claudia finds the boys, and the boats get thoroughly mixed up in the locks. A bloodthirsty pirate suddenly appears out of nowhere with his sailing ship, threatening the life of a crew member. The skipper and his friends have no choice but to flee. However, the biggest shock patiently awaits the returning vacationers at home. Author Claus Beese narrates the amusing and adventurous events of a summer sailing trip from the Aller to the waterways of Holland with a light touch and a relaxed pen.
