The film expresses that although modern people are faced with loneliness and fear, they are constantly exploring self-existence and seeking to break through the status quo. In the real society, the male protagonist feels very depressed and painful because he cannot find his own existence value and because of the emotional indifference between people. However, when he started living at the bottom of the cave, he began to actively seek change, to find a way to get out of this environment. When human beings truly realize that they are in crisis, the instinct to save themselves will force people to change. And once people start working hard, there is hope. This is also the human agency revealed by existential philosophy, that is, one of the central ideas expressed in the film.
At the same time, the hero and heroine of the film also form a very sharp contrast: the hero yearns for tangible freedom, while the heroine knows the true freedom of the heart. The male protagonist longs to become famous to determine his own existence value, but his dream is easily smashed by reality; while the female protagonist is strong and persistent in protecting his only residence in a very limited resource and environment, and obtains the The happiness she wants. The male protagonist in the film, from resisting the status quo to accepting the status quo, finally finds his own existence value in the seemingly hopeless status quo, begins new challenges, and begins to gradually understand the essence of existence.
