Me, a Groupie(1970)

She was Curious. She was Eager. She couldn't find any Satisfaction.

A beautiful blonde hooks up with a rock star, and after a night of sex and drugs, he leaves. She, though, has fallen madly in love with him, and sets out with her girlfriend across Europe to track him down. On the way, however, she gets mixed up with everyone from a gang of nasty bikers to a ring of devil worshipers.
