Hollow takes place 8,000 years after a nuclear apocalypse leaves the sky permanently covered in fallout. The earth, hollowed out for geothermal energy, has one last chance in a new form of power, but there are other parties who want to use the source for their own purposes. One such party is The Broker, who has hired a thief to infiltrate a secure facility and steal the power core. The thief is kept in the dark as to what he’s actually stealing, but once he figures it out, he goes rogue. The fate of the world is now in the balance, as two criminals fight to capitalize on it.
