He hotrods through the local town, where snooty college kids like him are the enemy. Their race results in a horrific collision and the total destruction of that diner in a special effects fireball. The diner is owned by Sobieski's family. So, when the court case wraps up and Klein and Harnett are sentenced to a summer's hard labour rebuilding the destroyed diner, that forces a closeness for all concerned, leaving room for the cliched romantic triangle to rear its ugly head. Kids fall in love.

Lots of banal things are tossed around in conversation. Adults are horrified. Sure enough, when the reel was corrected and re-screened, it played out as predicted. Not incidentially, this is one of those movies that would actually benefit from being upside down and backwards. Klein's performance is particularly galling.
