Earth's residents are unaware that the human species on Earth and countless other planets were established by families of alien royalty for the purpose of harvesting the resulting organisms to produce a type of youth serum for the elites on other planets. After the death of the matriarch of the House of Abrasax, the most powerful of the alien dynasties, her three children Balem, Kalique and Titus are fighting over the primary heir. Jupiter Jones, an unlucky caretaker of other people's houses, is identified as the genetic match of the murdered alien matriarch who used to rule Earth. Genetically engineered ex-military hunter Caine Wise shows up to protect her from alien assassins and take her to outer space, where the heirs of the Abrasax Dynasty are plotting against her.
