Bill begs his competitive-to-a-fault daughter Clarice to play fair as they arrive at what’s sure to be a contentious Cub Scouts Pinewood Derby tournament. Bill, having slept with (and ghosted) another parent, the vindictive Nance, is doing his best to stay out of the fray, but he can’t help but get involved in the drama after Clarice begins sabotaging her opponents’ cars for her own benefit. Calamity ensues as the other race attendees catch on to Clarice’s plans, but Bill and Clarice end up understanding one another better than ever before.
