In the organizer's words:

Do you know what the "Bloody Herring" is? "The Bloody Herring" was Captain Crinklebeard's proud ship. And Captain Crinklebeard, the terror of all seas. He could even sail against the wind! Sailors from the Skagerak to the Tasman Sea feared him. Every ship that came near him was boarded and robbed!
One day he attacked a small, inconspicuous ship that didn't promise much booty. He would have been better off letting it pass. Because on this ship he saw Molly. Molly - a little girl on her way to her grandma. And he will probably never forget this little girl again. Mary the Windcatcher tells you about the ancient and clever trick Molly used to save herself in the end.
