Following an unusual biology lesson ("Reproduction") given by Mr. Stuart (Tab Hunter), a substitute teacher, a gang of rival motorcyclists called the Cycle Lords (most of whom are members of the defunct Scorpions) led by Leo Balmudo (Dennis C. Stewart) surprise the T-Birds at the bowling alley.
The next evening while working at a gas station/garage, Stephanie is surprised again by the Cool Rider, and they enjoy a romantic twilight motorcycle ride.
