Peter and Tove are getting married. Since Peter only has three days' leave from his ship, they decide to go on their honeymoon to Copenhagen. After eating out in town, they check into a hotel for the night. The newlyweds quickly become embroiled in a crime drama. First, Peter finds a dead body in the bed. When the night porter finally arrives, the body has disappeared. The body is seen again in a large trunk, but disappears once more before the night porter can see it. Then Peter is kidnapped in the trunk.
