In the next 500 years, a group of people will live on a spaceship named "Quiet". Malcolm Reynolds, the captain of this ship, lost in a galactic civil war, and now he has nothing. Apart from this ship, there are only a group of absolutely loyal but disobedient subordinates: the second mate Zoe, Zoe's husband, pilot Walsh, mechanic Kelly and big Geller. Now that they have lost in the war, the only way to drag out an ignoble existence is to be bold. Therefore, in addition to engaging in some small businesses such as inter-satellite transportation, they occasionally do some harmless illegal acts. Although there are often some accidents, they are close to missing.
Until one day, two seemingly ordinary strangers boarded the ship and everything changed. It turns out that these two passengers, one is a young doctor Simon, and the other is Simon's sister Reeve, a girl who knows telepathy. They were hunted by the alliance that controlled the whole galaxy before they fled to this ship.
