An opportunist owner of a guesthouse is told that a famous filmmaker is an incognito guest of his institution. The latter observes the life of the vacationers for his next film. But the owner mistakes a tailor, another vacationer, for a director and to please him, hardens the regime in the guesthouse. To amuse the disappointed vacationers, Eliko, a waitress working in the diner, holds a concert that helps to reveal who a celebrity filmmaker is.
