In the very oldfashioned town of Ostend suddenly 13 suitcases are delivered to the hotel, with a note, that O.F. will be here soon and needs 6 rooms (the hotel just has five). This event, probably the biggest in 300 years, starts a small wave of modernisation, yet everybody is wondering who O.F. is. Journalist Stix and architect Stark have an idea how to use this event. They proclaim, that O.F. is a former citizen of the town, who became a millionaire abroad. They tell their fellow citizens that the town still needs modernisation, like better hotels, nightclubs, shops, etc. And soon, Ostend is a boomtown, then a capital. The architect, responsible for the new buildings is finaly allowed to marry the mayor's daughter, while Stix marries the cabaret star and the widowed mayor his new secretary. The only problem is, O.F. hasn't shown up, while finance experts from all over the world are trying to solve the depression problem.
Hutter (Gustav von Wangenheim), agente imobiliário, viaja até os Montes Cárpatos para vender um castelo no Mar Báltico cujo proprietário é o excêntrico conde Graf Orlock (Max Schreck), que na verdade é um milenar vampiro que, buscando poder, se muda para Bremen, Alemanha, espalhando o terror na região. Curiosamente quem pode reverter esta situação é Ellen (Greta Schröder), a esposa de Hutter, pois Orlock está atraído por ela.
