Alice in Acidland (1969)

"This is NO fairytale!"

Cute and perky college student Alice is invited to a "pool party" by Freida, a female teacher who is actually a lesbian and has designs on Alice. At the party Alice gets drunk, takes acid and immediately becomes a lesbian, taking a bath with Freida. Later Alice gets mixed up with LSD-addicted hippies, rape, more lesbians, more LSD, orgies, suicide, and having sex with guys in boxers.
