Fabian Bom has been sent by the Export Association to promote the Swedish export to Spain. He travels with the navy's cruiser to Barcelona, but his jealous fiancée Gullan has followed him in secrecy to keep an eye on him. In Barcelona the usually strict and virtuous Bom is surrounded by the local women and has a ball. He meets the young and zestful Linnea from Sweden.
