The main story of the film is that in 2517, after human beings exhausted the resources on the earth, they found a new galaxy. To provide human habitation, hundreds of planets have been transformed into the appearance of the earth by humans. The planets in these galaxies form the Star Alliance and want to control the entire galaxy. After a civil war similar to the American Civil War ended, many excluded humans were forced to come to a corner of the galaxy, and they could only rely on the most basic human life to make a living. Veteran Malcolm Reynolds is one of them. He and a group of marginalized people drive a Firefly-class spacecraft Serenity to find another way out in the universe.
