Reflections (1987)

Mihajlo, an introvert piano teacher starts romance with a pretty careerist who teaches modeling at the university in Belgrade where they both work. His feelings are awakened after a long period, but this relationship makes him see the flashbacks, as well as yet unseen images that remind him of his troubled childhood - as if he experienced this already. When their university wins a contest to hold public TV performance, Mihailo fails to play the piano on the decisive night and she dumps him. The boiling point is about to come.
