Four of the best Dirt Modified racers in Kansas City, Kansas, also happen to be the fiercest of rivals. Every Friday they put their lives on the line and battle it out at 120 mph at Lakeside Speedway.

Tim Karrick and Dan Charles race to repair their badly damaged cars, while Justin Boney can't catch a break after losing again. Meanwhile, Tom Charles is offered a trial run at a sponsorship.

This town is too small for four larger-than-life racers. The rivalry heats up as they cross paths everywhere from the car wash to the county parade. Then, one team's disappointing performance causes major friction.

The racers pack up their trailers and head to the Central Missouri Speedway to take on their cross-state rivals. This violent track is smaller and more dangerous, and tensions mount between Tom and Dan over a vital race decision.

Tim reunites with longtime friend and Nascar superstar Clint Bowyer. Meanwhile, Justin can't catch a break, and Tim challenges Tom to a head-to-head autocross event. Also, Dan mentors 16-year-old race prodigy, AJ Tice.

The racers prepare for the most prestigious and financially lucrative race of the year: the Tom Karrick Memorial. Tim Karrick vows to win the race, which was named to honor his father.
