It cannot be said that the two actors Kurt Karlsen and Valdemar Hansen are particularly successful. The audience often has to ask them to stop, and financially things are not going well either, so they have to flee from their hotel bills. In a provincial town, Professor Andersen has just died, and when the two actors arrive in town at the same time, they are mistaken for the professor and his assistant and are given accommodation at one of the town's hotels as guests of honor. Then events take a turn for the worse. A bank director, a lawyer, and a contractor are very eager to see the late professor's invention continued, as the formula was lost when the professor died. Who will win in the end? The suspicious businessmen, the two actors, or two young people who love each other? And how many times will bank assistant Johansen lose his job?
