In the year 2092 Earth has become nearly uninhabitable. The UTS corporation builds a new orbiting home for humanity that mimics the natural processes on Earth; however, only a chosen few are permitted to ascend and become UTS citizens, while those remaining on Earth breathe in polluted air and fight to feed their families. Under guidance from the UTS founder and CEO, James Sullivan, the company is working towards making Mars a new Earth, growing genetically modified plants on the planet and turning it into a hospitable environment for humans.

To regulate the population in orbit and keep an eye on the non-citizens, UTS governs them via a strict set of rules and taxes. Many non-citizens from all across the globe work as space sweepers, collecting space debris floating in Earth's orbit and selling it to the company for survival. The plot follows such a crew of space sweepers and their ship, Victory.

The Victory's crew has Kim Tae-ho, Tiger Park, Bubs (An Android) all led by Captain Jang. Tiger Park handles the ships machinery and was a drug baron on Earth. Bubs used to be a robot soldier but now helps repair the ship and cast the net for space junk while saving up to get a complete skin graft. Captain Jang was one of the child geniuses sponsored by UTS and created several hi-tech inventions for the company but, after discovering the company's true workings, became a pirate and tried to assassinate James Sullivan. Her crew was killed and Sullivan survived, so she changed identities and had an eye transplant. Tae-ho, once a child soldier, is on a hunt for his daughter (Sun-ni) who was lost, ejected into space. His sole life aim is to pay for the authorities recovery team to locate her body tracker before she drifts out of orbit and gets lost in space forever.

After picking up a car floating in orbit, they discover a child in it. News reports say that she is a robot named Dorothy, and has a weapon of mass destruction inside her created by the terrorist group Black Fox. The crew also finds a smartphone in Dorothy's bag with several missed calls from a Kang Hae-yo on it. They call back and, assuming the other party to be Black Fox group, they negotiate two million dollars for returning Dorothy. Tiger finds Dorothy drawing in his cabin and starts a conversation with her, he finds himself drawn to her.
