Welcome to Butler, Missouri, where the wheeling and dealing at Max Motors never stops. Owner Mark Muller is an old-fashioned businessman with an unorthodox style that always shocks and scares his baby brother, Chicago radio legend, Erich "Mancow" Muller, who's a partner in Max Motors. Despite Mancow's pleas to play it safe, Mark promises his staff he'll blow up a car "like in the movies" if they meet their monthly sales goal.

Max Motors' ace salesman, "Cowboy" Matt Harvey is in trouble with the law and turns to Mark for help. If Matt can clean up his act, and get into riding like he did back when he was a professional bull rider, Mark will bail him out. Meanwhile, Mancow learns the hard way how to do business in Butler when he spends a day out with the repo team.

In an attempt to bring some big city pizzazz to the dealership, Mancow bets Mark that a "Midnight Madness" sale will generate a ton of business for Max Motors. What Mancow doesn't understand is that things work a whole lot different in the country. Meanwhile, Mark hires a new personal assistant, Jason, who has to deal with being "the new guy" at work.

When Mancow shows up in Butler with a toy drone, Mark hatches a plan to throw one of his most creative sales promotions ever–it's an elaborate scheme involving aliens, UFO's and out-of-this-world prices. But will the staff meet the challenge set by the boss?

In order to create buzz at the dealership, Mark collaborates with the local Sherriff's department to host a gun buyback event where the community can trade in their unwanted weapons for cash. Old and dangerous weapons are destroyed on the spot and Mark adds a couple of beauties to his private collection. Meanwhile, Mark's son, Max turns to his father for a job. Against his better judgment, Mark gives him a shot.
