It is the late 21st century, when 80% of mankind have been infected with a virus called HPV2 (human parvovirus 2), or P2, whose spread was accelerated with the discovery and use of synthetic blood.
Uninfected people reside in "Clean Bill of Health" (CBH) zones within cities to avoid contact with the sick, for vamping (murder for the purpose of blood theft) is a major risk for healthy individuals.
Dallas is now set on revenge and recruits a team funded by himself and a mafia boss to rob the First National Blood Bank on the moon.
The blood contains extremely advanced nanomachines which activate an ability to live longer, and be far more resistant to human limitations such as the need for food, water and oxygen; it enables them to survive in a state of suspended animation for years at a time.
While Dallas and his crew are asleep on their way back to Earth, the supercomputer (unbeknownst to the humans) activates their new hibernation state and sets their course to deep space.
