Cam decides to leave his father to join Linksy as a chance to prove his worth and win races. When Cam tells his father about his choice to join Linsky, Sam is enraged and warns that Linsky is a snake before firing his own son from the garage.Feeling down from Cam's defection, Sam spends the night drinking his woes away.

With Sam reclaiming his title as champion racer, Linsky feels threatened by Sam and wants Cam to crash into Sam's car. Unable to crash into his father, Linsky has another racer stage a crash at the next race. Dunn causes Cam to spin out and Sam crashes into Cam's car onto the side.

With both cars severely damaged, they need a new car to get back into racing. Throughout this time, Sam has kept the 1970 Mustang that killed his wife. Because of sentimental value, he could never sell it. However, in order to buy a new dirt Late Model for Cam to drive, which costs about $80,000, Sam decides to sell his car to Linsky. Now devoting all his energy into building the new car, the Munroe family pools their efforts into getting the car ready and supports Cam's return to the circuit.Linsky wants to beat Sam to finally prove who is the better racer; he has to settle with racing Cam instead.
