A movie about Valerie Solanas, 1960s radical feminist who worked with the pop artist Andy Warhol and - you guessed it - tried to kill him. Sewer-mouthed tomboy who works as a whore and hates men and femininity, she writes SCUM manifesto - no, not her biography, albeit the name is apt, but militant feminist ramblings - and tries to do the murderous deed. (No, it is not really a spoiler, it is mentioned in the title.) Albeit suffering later from paranoia and mental illness, which is always a tragedy, her totally disgusting personality makes her anything but sympathetic. Not that other characters would be more interesting or likable. Blech.
