Quick Answer

Murder Weapon is a 1989 American horror-thriller film directed by David DeCoteau about two mobster daughters who, after release from a sanitarium, throw a party inviting their ex-boyfriends—only for the guests to start disappearing.

Programmer's Pick

Mobster bloodlines, slasher mayhem, and a party you wouldn’t RSVP to twice—Murder Weapon is a pulpy cocktail of 1980s excess and exploitation. Where else do you get female psychopaths, bare-chested male victims, and a sanitarium backstory all before dessert?
