A spectacular shipwreck in the Øresund is the focus of a new exhibition at the Maritime Museum, but the adventure comes to an abrupt end when one of the divers working on the project is found dead at the local diving club. Dan and Flemming must delve into the legends, not only about the ship, but also about the deceased himself. Dan has moved into the annex with Marianne and Flemming, whilst he longs for Josefine, who remains in Sweden with her ex-husband and stepsons.
