Fresh off their huge win against NOLA, JJ Da Boss and the MSO hit the streets after getting called out by Quinn Shireman and his team from Kentucky. Quinn has a big mouth and the fast cars to back it up, forcing the MSO to go all hands on deck for a win.
Race night against the Kentucky racers continues with JJ throwing a curveball and Kentucky falling behind. A face-to-face confrontation emerges on the course and tempers are boiling out of control but MSO is determined to prove why they're the best.
Race night gets rowdy when Memphis welcomes a new racing group from Virginia. The newcomers talk a big game but run out of cars after only a few races, leaving Molly and Ole Heavy without a race until Virginia can fix their cars and return.
The Memphis family loads up their cars and heads to Battlefield Dragway in Mississippi for one of JJ's famous arm-drop competitions. Thirty-five small-tire-car racers begin round one in this exclusive event, but only one will take home the grand prize.
