The American boat is on its way to Gothenburg. On board are the Swedish-American millionaire Fridolf F. Johnson from Detroit (Håkan Westergren) and his male secretary of the same name (Fridolf Rhudin). The millionaire stays hidden in his cabin with the secretary and does not appear on deck. A journalist arrives out at sea by airplane and asks for an interview, which the millionaire refuses to agree to. The journalist disguises himself as a steward, puts on a hidden camera (a spy camera) in the buttonhole, enters with a tea tray and photographs the wrong person - the secretary.
