Sam Oliver is a slacker who still lives with his parents and who is a below-average employee at The WorkBench. He dropped out of college after only six months because it made him "sleepy." But the day of his 21st birthday is life-altering, as Sam learns that his parents sold his soul to the Devil before he was born. Now it is his responsibility to recapture souls escaped from Hell with the aid of vessels: magical objects specifically designed for the confinement of a soul. His first assignment is a fireman who enjoys setting fires. Along with his friends Sock and Ben, Sam goes after his first target using his new telekinetic power and a magical Dirt Devil vacuum vessel, while simultaneously trying to kindle a romantic relationship with his co-worker Andi.
