Werewolves on Wheels

Werewolves on Wheels is a 1971 American exploitation film directed by Michel Levesque and starring Stephen Oliver, D.J.

"As it is, the story takes up the tracks of a California biker gang, the Devil's Advocates, as they speed across a barren highway on a drug-infused journey of undisclosed intent.

Much to their initial pleasure, they are fed by a kindly group of hooded priests before settling into a deep, inebriated stupor.

That night the cultists cast a curse on the biker leader's girlfriend that makes her turn into a werewolf after nightfall; she soon infects her boyfriend.

In many scenes, footage was used of real bikers with no experience or training in acting going about their lives as normal.
