based on what you had said in your comment, the movie A Rebel Without A Cause… similar theme to what you are implying.

“Rebels against No Cause
Let’s move now to films with lower-story worldviews. The classic Rebels without a Cause (1955) was one of the first adolescent-angst films. The adults in the film preach a bleak, nihilistic vision of reality–and then seem nonplussed when young people actually live out what they have been taught.

Toward the beginning, a scientist at a planetarium tells an audience of students that ultimately the earth and everything on it ‘will disappear into the blackness of space from which we came–destroyed, as we began, in a burst of gas and fire.The heavens are still and cold once more.’ The implication is that human life has no ultimate significance. ‘In all the immensity of our universe and the galaxies beyond, the earth will not be missed,’ the scientist continues. ‘Through the infinite reaches of space, the problems of man seem trivial and naive indeed. And man, existing alone, seems himself an episode of little consequence.’

This is outright preaching for lower-story worldview: Human life is trivial, temporary, and meaningless. The planetarium show ends with a dramatic red burst of gas and fire, signifying the end of the world.

The young people in the movie are angry and impatient at their parents’ failure to give them any cause worth living for. The main characters, played by James Dean and Natalie Wood, cling to one another as though their love might create a small enclave of warmth and light in the face of a dark and meaningless world. Yet the film ends with a shot of the scientist arriving at the planetarium the next morning to continue his work. The image suggests that the scientist’s bleak message will prevail in the end. The young people’s rebellion, like all of human life, is ultimately pointless.”
