When Bubba and the team are hired by TNT Amusements to build a custom Bubba-Q out of a real pinball machine, things get a little heated. The team must find a way to build a smoker that will cook the four phases of barbecue but still have some of the functions of a pinball machine. When a test puts them back to square one, the team must figure out a way to get this pinball barbecue finished in time for the big event.
