Oksana (played by Sofia Rotaru) is a young and beautiful Carpathian girl. On the "Donetsk-Verkhovyna" train she becomes acquainted with a young miner from Donetsk called Boris. The travellers fall in love, but are parted when they arrive at their destination. In the Carpathian mountains their paths diverge, but Boris (played by Vasyl Zinkevych, soloist of the instrumental band "Smerichka") discovers where she is staying. The couple meet again and rekindle their love. Their friends invite them to perform in a concert for vacationers at a mountain resort, where they sing about their feelings for each other.
