Pirates, mermaids, and a treasure - Konny and Kriemhild embark on a road trip into a maritime adventure where blood and tears of laughter flow. Three strangers break into Konny and Kriemhild's guesthouse and demand that the two sisters hand over the millions owed to them by the commodore, Kriemhild's deceased captain husband. Did the commodore really illegally unearth an ancient treasure, swindle his crew, turn the treasure into cash, and stash it away somewhere? In search of the truth, Konny and Kriemhild - with the commodore in a handheld vacuum cleaner and the naked cat Amenhotep in a transport box - set off on a road trip to the far north. Along the way, the provincial women encounter tough bikers, hardcore stoners, dealers, and a woman who claims to have been the commodore's lover. A rollercoaster ride.
