The Big Cube

When a vindictive heiress is forbidden by her stepmother (screen legend Lana Turner, "The Postman Always Rings Twice," TV's "Falcon Crest") to marry her boyfriend, a whacked-out drug dealer, she conspires to drive her insane. Her choice of weapon -- a "big cube" of LSD. Co-starring Academy Award-winner George Chakiris ("West Side Story").
