In the 2190's, Earth has become a foggy, distant memory for most of humanity. But for the unlucky survivors on the surface, every day reminds them of the atrocities that led to Earth's downfall.

The great cities of Earth have descended into a complex, interweaving web of gang wars and despotic opportunists. In the remnants of Malibu, a small group of young people, orphaned by the great tragedy, have created a humble commune, where they live collectively and act as a peacekeeping force for the ruined city of Los Angeles.

A young woman named Sarasvati, who grew up in the commune, has made a name for herself as a ruthless warrior who fights for justice. Her relationship with her girlfriend, Zoe, is strained when the Vanguard, the hate group that persecuted her when she was a teenager resurfaces and wants her, and the rest of the commune, dead.

Among the chaos, an affluent family from the planet Venus, seemingly falls out of the sky and begs Sarasvati and her friends for help in escaping the dangers of Earth and going to Titan, where patriarch Everett Lambert hopes to find a promising career in politics. When the Vanguard learns that the Lambert Family is on the surface, they focus all of their efforts into eradicating them, lest they escape with the fugitives and spread word of the conspiracy keeping Earth's demise a secret from the rest of humanity.
