When well-to-do Bess Denyar learns she’s adopted, she’s stunned. Even more so when she is reunited with her birth parents, who run a drag-racing team.

Angry with Margaret for lying to her all these years, Bess concentrates on getting to know Wayne and Julie, her real parents.

When Wayne and Julie give Bess a “Hot Lap”-a ride in a V8 Supercar-to make up for all the birthdays they've missed, Bess is shocked to discover that she is a natural.

Bess arranges a lunch for her two mothers, Margaret and Julie, which ends in disaster when Julie, unaware of Bess's allergies, puts peanuts in the meal.

While Bess is thrilled that her two families are coming together, Danny freaks out when he finds out that Shawn and Edwina have skipped school and gone dirt-bike riding.

After backing into another car, Wayne is forced to take a driving test because of his glass eye. When he fails the reverse park component of his test, Wayne is crushed.

Margaret is not taking her diabetes seriously, so when Brianna qualifies as a fitness instructor, Bess sees a chance to help both her adoptive mother and older sister.

Danny is cross because Bess cancels their anniversary weekend to go to the Drag Racing Championships, but Bess really wants to support Team Wheeler.
