The Nameless Star (Russian: Безымянная звезда, romanized: Bezymyannaya zvezda) is a 1979 Soviet romantic comedy television film directed by Mikhail Kozakov and based on the play The Star Without a Name by Mihail Sebastian.

It is a quiet town where all the residents know each other and the passage of the "Bucharest-Sinaia" express train is considered a major event.

The express train never stops: it passes through town once in the morning on the way to Sinaia, and once during the evening on the way back to Bucharest.

The residents of the town regularly congregate at the train station to watch the express pass and to speculate about the faraway lives of the passengers.

One evening, the owner of the town's department store Mr. Pascu returns from Bucharest with various specialty orders for the residents.

Miroiu rushes to the train station, as Ispas must remain there until the evening "Bucharest-Sinaia" express passes.

She forces her husband to explain what happened after smelling Mona's perfume in the station office.

Unable to reveal her true feelings when asked why, Cucu instead says that she wants to know where Miroiu acquired 22,000 lei to purchase his new book.

The book is a 17th-century astronomical treatise, which Miroiu was able to afford by living an intensely frugal lifestyle.

Mona asks to see the star, but Miroiu explains that it's not visible: he discovered it through mathematical reasoning.

Mona doubts him, so Miroiu attempts to show her where the star is in the sky from his balcony, but his aggressive explanation frightens her and she retreats back inside the house.

He has written a symphony which he wants to perform, but it requires an English horn which costs 4,500 lei and which the town does not have.

At Mona's request, Udrea performs a short version of his symphony using his voice.

While he is away, a man named Grig arrives at his house and the details of Mona's life are filled in.

Udrea returns to tell Miroiu that Grig gave him 5,000 lei to buy an English horn.
