It's the 1930s. The Republic Day Ball is in progress in Zonguldak, a coal mining town in Turkey. Among the invited guests are the newcomers to this small and boring town: Halit, an engineer; his gorgeous wife Mükerrem, and Halit's sister and unwanted household member Seniha. During the ball Seniha realizes she would be the one who determines the destiny of beauty.
