Edgar Wiggins, a disgraced former seminary student, is desperate to find a way to answer what he believes is his higher calling. He thinks he’s found it in a seminar hosted in a hotel conference room by the Soul Plumbers, who have a machine that could be the secret to delivering souls from Satan. Edgar’s too broke to buy in, but that’s not enough to stop this true devotee: he steals the blueprints and builds a pirated version with what components he can afford on his gas station attendant salary. Then he goes after a demon, misses… and ends up pulling out something much worse.
