From the show:

They’re coming for your souls. They’re coming tonight. That would be a scary thought if “They” weren’t a couple of greenhorn demons more concerned with socializing than doing their jobs. Lisa and Dave are siblings in a tight spot– if they can’t find a loophole in their infernal contract, they’re going to hell. Tonight. But with an increasingly eccentric cast literally breaking down their door, they’re going to need to think outside the box. SOUL SURVIVOR is first and foremost a raucous comedy exploring an obnoxious, bureaucratic hell. Any touching moments or examination of morality is purely accidental.
