In episode 4 titled 'Dale', father and son unite on the track at the 2001 Daytona 500, leading the pack in a pivotal race that becomes a turning point for both the Earnhardt family and NASCAR as a whole.

Episode 4 builds up to the emotional 2001 Daytona 500 race, showing it as a significant moment that deeply affects the family, marking a turning point in their lives and in the sport, with the aftermath leading to triumph and closure for Dale Jr., the racing team, and friends and family.

The series explores complex family dynamics, including Dale Earnhardt's demanding career impacting his children, the entrance of Dale Jr., Kelly, and Kerry into racing, and tensions involving Earnhardt's wife Teresa, especially her difficult relationship with Dale Jr. and Kelly after Dale Sr.'s death.
