All the elements in the film point directly to loneliness, the loneliness in the noise.
So we saw the protagonist who was shuttled in the city. He had seen all kinds of passengers and all kinds of life, but he was still lonely. The last love for the society in his heart made him unable to integrate into it, so after failing to integrate again and again, he decided to resist.
The society in the film points directly to the United States in the 19670s. After the Great Depression, people have not recovered their vitality, the popularity of hippies, and the chaos of social order. The Vietnam War is not over yet, the depravity of teenagers, drugs, shootings, robbery, prostitution.
The male protagonist hopes to contribute to the country, but has never waited for the application form sent by the federation. He decided to kill the country, and after the failed attack on the elector, he immediately went to rescue the girl with a mortal heart, but the police didn't shoot.
Still hopeful, he saves a runaway teenage girl from a pimp and a rural northern family. For the first time he felt that he had realized his self-worth, and he became a hero among the very few.
As a result, he was redeemed, and he found a new belief in the confusion and chaos of a society. In the end, the woman he liked got into his taxi, her attitude had changed, and he was relieved.
He forgave all the confused and indifferent.
