For the first 20 years of his life, Sam (Bret Harrison) wondered why his parents went so easy on him.  Whether it was school, sports or career choices, Sam's mom (Allison Hossack) and dad (Andrew Airlie) always let him get by with the least possible effort. As a result, Sam skipped college, took a dead-end job at the local Work Bench home improvement store and now wastes endless hours playing video games.  But everything in his slacker world is set to change the day Sam’s turn 21 and discovers the ungodly reason his parents let him slide: they sold his soul to the devil before he was even born.

Though his guilt-ridden parents try to explain the circumstances that led them to the forfeit his soul, Sam can't wrap his mind around what is happening to him. He's always been the under-achieving son, while his younger brother Kyle (Kyle Switzer) was pushed to get straight A's, excel at every sport and join every club. Kyle resents the easy ride Sam has enjoyed, and Sam can't help but feel jealousy over Kyle's achievements.   What neither brother realises is that their lives have been shaped by forces they can't yet begin to understand.

When Satan himself (Ray Wise) drops by to personally explain that Sam must now serve as his bounty hunter, tracking down evil souls that have escaped and returning them to Hell, Sam refuses to accept his bizarre fate. After getting just a glimpse of Satan's temper, however, Sam realizes that breaking a deal with the devil has consequences that are very, very bad. Still, Sam is fascinated by the devil's charm and his flattering insistence that Sam is full of untapped potential.

Armed with a constantly changing series of vessels -- starting with a Dirt Devil mini-vacuum -- to collect the escapees, Sam finds that his new line of work is dangerous and frightening, even with the goofball help of his friends and co-workers Bert "Sock" Wysocki (Tyler Labine “Invasion”) and Ben (Rick Gonzalez)  along with Sock's former-girlfriend-turned-paralegal, Josie (Valarie Rae Miller, "Dark Angel"). Sock has been Sam's closest friend and slacker role model for many years and was the first person Sam turned to with the news about his gig with the devil.

A perennial adolescent who attended high school on the six-year plan, Sock is perfectly happy with his life and his job at The Work Bench, where he is a thorn in the side of the assistant manager, Ted (Donavon Stinson), Sock thinks Sam's news is totally cool, and is happy to help with Sam's assignments from Hell.   Ben, on the other hand, immediately grasps the seriousness of Sam's situation.   A college student and the son of a reverend, Ben is also on board to help, but he knows that dealing with the devil is no game.
