Hi-Fi (1987)

From the DVD booklet:
Through fragments of Boris’s life and his son Matej, the film expresses the conflict of generations, the already existing gap because of their ideological coloring as well as their different opinions towards the capability of living, worthy of a human being. After several years spent in prison for political reasons, Boris comes back home. In his apartment, where after the divorce with his wife he lives alone, he finds that his son Matej moved in. His son is already an adult and he’s trying to make a living as a pop-musician. He sets up an improvised sound recording studio in his father’s apartment. Boris doesn’t like Matej’s life-style and his behavior toward his girlfriend and his other friends in general, as he find it a life without sense, without plans and ideals.

He blames his ex-wife for such a transformation of his son. … So, there is nothing left to him but to “turn” his son back to the “real”, and to show him that a man should spend his time being worthy. Boris tries to build a relationship with his son but he doesn’t succeed.

Finding himself helpless, he introduces a cruel and strong discipline into his son’s life…
