Richard "Fitz" Fitzpatrick, morally bankrupt top salesman of pre-owned automobiles for 9 years running, hits rock bottom when he crashes a GT on a test drive, puts a woman in a coma, and wakes up to find he's grown a conscience - a living/breathing hanger-on named Larry, who joins Fitzpatrick Motors as a do-gooder salesman, and threatens to undercut Fitz' debaucherous way of life...

After a failed hit on Larry's life, Fitz's only option is to get rid of him by proving Larry's a crazy person. After all, he claims to be his conscience. Meanwhile, Larry tries to purge Fitz of drugs and alcohol. But by the time Larry rallies the Fitzpatrick family for an intervention, Fitz's own sanity begins to dwindle in the throes of the DTs, and he decides to take whacking matters into his own hands...

When Fitz discovers his Father Ken is leaving Fitzpatrick Motors to Larry in his will, he has no choice but to prove Larry is NOT his long lost, responsible brother. And the only way to do it is a quick visit to his absentee, alcoholic mother Elaine. On Fitz's quest for closure however, he ends up at Elaine's weekly key party. When he can't find the answers he needs, he steals her car. Meanwhile, demented Junior Survivalist Kara builds her now growing attempted vehicular manslaughter case by blackmailing Josh with a compromising cell phone.

Fitz quickly unloads Elaine's car in hopes of putting their broken relationship behind him for good. But Larry is convinced it was a desperate plea to get her back in his life. Unfortunately for Fitz, that's exactly what happens. After manipulating Larry into a family reunion, Elaine gets Fitz on board to scam the Ruptals and get the car back. But its all part of a Long Con Elaine concocts to finalize her divorce and rid herself of all things Fitz once and for all...

When Larry and Meghan buy Ken a birthday present, Fitz scrambles to come up with his own gift to blow Meghan's out of the water. But the only thing they have in common is cars and porn. So Fitz shoots a car-themed porn with Ken's favorite classic porn star Candy Box. But she's a little older than Fitz remembered. When her kids show up, and her back goes out, Fitz has to man-up and save the day. By co starring with Sonja...
