The Big Cube

Broadway star Adriana Roman (Lana Turner) weds business tycoon Charles Winthrop (Daniel O'Herlihy), which further strains the relationship between him and his rebellious teen daughter, Lisa (Karin Mossberg), of whose drug-dealing hippie boyfriend, Johnny (George Chakiris), Winthrop disapproves. When Winthrop dies unexpectedly, Johnny convinces Lisa that Adriana murdered him, and together they conspire to drive her insane by lacing her sleeping pills with LSD.
