Viva (2007)

They were housewives seeking kicks, in a world of swingers, orgies, booze and sin that was the sexual revolution!

Abandoned by her husband, Barbi is dragged into trouble by her girlfriend, who spouts women's lib as she gets Barbi to discard her bra and go out on the town. Barbi becomes a Red Riding Hood in a sea of wolves, and quickly learns a lot more than she wanted to about nudist camps, the hippie scene, orgies, bisexuality, sadism, drugs, and bohemia.
