Two Husqvarna 400s wheelie through a meadow, the lead bike ridden in a panic as a killer on the second reels it in. They crest a ridge. The bike ridden by the killer washes out and he tumbles to the ground. The pursued goes hurtling off a cliff. Stuntman Alan Gibbs is yanked off the motorcycle, just in time. It plunges off the precipice without him, a mannequin sitting in his place until the bike hits the ground and a napalm bomb attached to the Husky goes off.
