During the year 2092, Tae-ho, Captain Jang, Tiger Park and an android named Bubs are a crew of space sweepers who live at an orbiting space station created by the UTS corporation after Earth becomes uninhabitable. Under the leadership of Sullivan, UTS has also created artificial planetoids for a select group of humans, who live idyllic lives. UTS has also terraformed Mars, intending to colonise the planet. By contrast, 90% of humanity lives in poverty and squalor on a dying Earth.
Tae-ho's crew struggle with mounting debts, loan sharks, and competition from other space sweepers. During their work, Captain discovers a child robot named Dorothy, who contains a weapon of mass destruction purportedly created by the terrorist group "Black Foxes". They negotiate a ransom for returning Dorothy, but their plan is foiled when UTS soldiers stage a massacre at the club where the exchange was supposed to take place. Following the massacre, the UTS frames Tae-ho and his crew as terrorists.
While the crew initially view Dorothy as an object, their feelings towards the girl soften. For Tae-ho, Dorothy reminds him of his adopted daughter Kim Su-ni, who was blown out into space during a space accident. Tae-ho and Jang were once UTS soldiers but defected after being forced to kill refugees fleeing Earth and incurring the wrath of Sullivan. Bubs and Park also befriend Dorothy.
Tae-ho and his group come into conflict with the Black Foxes, led by Karum. Following a confrontation on a space station, Karum reveals that the Black Fox are not terrorists but rather environmentalists seeking to return Dorothy to her father Kang Hyeon-u, a dissident scientist who has fallen afoul of Sullivan. Dorothy is revealed to be Kang Kot-nim, a human who was injected with nanobots by her father in an attempt to heal her. Sullivan wants Kang because her nanobots can interact with other nanobots, making her a superweapon.
Sullivan's UTS forces track down the two groups and kill the Black Foxes. However, he spares Tae-ho, Jang, Park and Bubs due to his past relationships with the former two. In return for Tae-ho surrendering Kang Kot-nim, Sullivan grants the space sweepers an amnesty and a lump sum to cover their debts. Tae-ho uses his share of the money to fund an expedition to find his lost daughter Kim Su-ni but feels guilty about betraying Kang.
Sullivan considers Kang's nanobots as a threat due to their potential to restore the Earth and render his idyllic planetoids irrelevant. Because only a direct thermonuclear blast can destroy the nonobots, he intends to destroy the nanobots, Earth, and Kang all at once by sending them with the bomb to crash on Earth. Tae-ho's team rescue Kang but struggle to disable the bomb and stop the collision. They enlist the help of the other spacers in stopping the collision. During a climactic battle with Sullivan, Tae-ho and his companions manage to detach the bomb from the orbital factory. Sullivan is killed when the bomb collides with his spaceship.
Following the battle, UTS makes reparations to those affected by Sullivan's crimes. Kang Kot-nim is adopted by Tae-ho and his crew, who are richer and settle scores with their crooked financial manager. Tae-ho also reconnects with Kim Su-ni on the astral plane while Bubs obtains a female human body.
